Breakthrough In Automatic Handwritten Character Recognition Sans Deep Learning (technologyreview.com)
subh_arya writes: Researchers from NYU, UToronto and MIT have come up with a technique that captures human learning abilities for a large class of simple visual concepts to recognize handwritten characters from World's Alphabet. Their computational model (abstract) represents concepts as simple programs that best explain observed examples under a Bayesian criterion. Unlike recent deep learning approaches that require thousands of examples to train an efficient model, their model can achieve human-level performance with only one example. Additionally, the authors present several "visual Turing tests" probing the model's creative generalization abilities, which in many cases are indistinguishable from human behavior. -
Peter Thiel: We Need a New Atomic Age
HughPickens.com writes: Peter Thiel writes in the NYT that what's especially strange about the failed push for renewables is that we already had a practical plan back in the 1960s to become fully carbon-free without any need of wind or solar: nuclear power. "But after years of cost overruns, technical challenges and the bizarre coincidence of an accident at Three Mile Island and the 1979 release of the Hollywood horror movie "The China Syndrome," about a hundred proposed reactors were canceled," says Thiel. "If we had kept building, our power grid could have been carbon-free years ago. Instead, we went in reverse."
According to Thiel, a new generation of American nuclear scientists has produced designs for better reactors. Crucially, these new designs may finally overcome the most fundamental obstacle to the success of nuclear power: high cost. Designs using molten salt, alternative fuels and small modular reactors have all attracted interest not just from academics but also from entrepreneurs and venture capitalists like me ready to put money behind nuclear power. However, none of these new designs can benefit the real world without a path to regulatory approval, and today's regulations are tailored for traditional reactors, making it almost impossible to commercialize new ones. "Both the right's fear of government and the left's fear of technology have jointly stunted our nuclear energy policy," concludes Thiel. "supporting nuclear power with more than words is the litmus test for seriousness about climate change. Like Nixon's going to China, this is something only Mr. Obama can do. If this president clears the path for a new atomic age, American scientists are ready to build it." -

The Neuroscientist Who Tested a Brain Implant On Himself (technologyreview.com)
An anonymous reader writes: Our understanding of the brain has come a long way in the past thirty years, but most brain-related medical procedures remain incredibly complicated and dangerous. Neurologist Phil Kennedy has been working on brain-computer interfaces since the 1980s. He was most notably involved in letting a patient with "locked in" syndrome interact with the outside world through a brain-controlled computer cursor. But the FDA has gradually ramped up its safety demands, and in the past decade they've shut down Kennedy's research. So he did what any determined inventor would do: he went to a hospital in Belize and had surgeons there implant electrodes on his own brain so he could continue his research.
"After returning home to Duluth, Georgia, Kennedy began to toil largely alone in his speech lab, recording his neurons as he repeated 29 phonemes (such as e, eh, a, o, u, and consonants like ch and j) out loud, and then silently imagined saying them. ... Kennedy says his early findings are 'extremely encouraging.' He says he determined that different combinations of the 65 neurons he was recording from consistently fired every time he spoke certain sounds aloud, and also fired when he imagined speaking them—a relationship that is potentially key to developing a thought decoder for speech." Eventually, Kennedy had to have the implants removed, but he hopes the data he gathered will help push the FDA toward supporting this research once more. -
Robots Teach Each Other New Tricks (technologyreview.com)
schwit1 writes with this story from the MIT Technology Review about a robot at Brown University who was taught to perform a task from another robot at Cornell. According to the article: "the ability to acquire and then share knowledge is a central component of human culture and civilization. A small milestone in the exchange of robot knowledge has now been demonstrated by two bots working in different academic research labs. Researchers at Cornell University previously devised an online game, called TellMeDave, through which volunteers can help train a robot to perform a task and associate different actions with commands given in everyday language. By guiding the robot through a task, a volunteer trains a machine-learning algorithm so the robot can perform the task again. And this learned behavior is stored in a central repository called RoboBrain that's accessible by other robots (see 'The World's First Knowledge Engine for Robots')." -
An Algorithm For Better Password Checking (technologyreview.com)
New submitter della writes: Password checkers — those things that tell you whether your password is strong or not — are good: various studies have found that they make users choose better passwords. Unfortunately, nowadays attackers use probabilistic strategies based on natural language processing to guess passwords earlier, and most checkers consist of heuristic rules that don't reflect well probabilistic attacks. To do better you could in theory simulate the attack, but if your password is not that bad, that would be very expensive or just unfeasible.
In a paper I wrote with Maurizio Filippone and presented at ACM's CCS conference, we show how you can take an attack model and a password, and through a simple formula come up quickly with a reliable estimation of how many guesses that attack would need to guess the password. You can use this to roll a better password checker, or — as we've also done in the paper — to compare different attacks. -
(Over-)Measuring the Working Man
HughPickens.com writes: Tyler Cowen writes in MIT Technology Review that the improved measurement of worker performance through information technology is beginning to allow employers to measure value fairly precisely and as we get better at measuring who produces what, the pay gap between those who make more and those who make less grows. Insofar as workers type at a computer, everything they do is logged, recorded, and measured. Surveillance of workers continues to increase, and statistical analysis of large data sets makes it increasingly easy to evaluate individual productivity, even if the employer has a fairly noisy data set about what is going on in the workplace. Consider journalism. In the "good old days," no one knew how many people were reading an article, or an individual columnist. Today a digital media company knows exactly how many people are reading which articles for how long, and also whether they click through to other links. The result is that many journalists turn out to be not so valuable at all. Their wages fall or they lose their jobs, while the superstar journalists attract more Web traffic and become their own global brands.
According to Cowen, the upside is that measuring value tends to boost productivity, as has been the case since the very beginning of management science. We're simply able to do it much better now, and so employers can assign the most productive workers to the most suitable tasks. The downsides are several. Individuals don't in fact enjoy being evaluated all the time, especially when the results are not always stellar: for most people, one piece of negative feedback outweighs five pieces of positive feedback. -
Damaged Spinal Cord "Rewires" Itself With Help of Electrical Stimulation
the_newsbeagle writes: Many prior experiments that tried to restore function after a spinal cord injury have used electrical stimulation to replace the signals from the brain, essentially implanting a replacement nervous system. But a new project instead used electrical stimulation to encourage the natural nervous system to adapt to a severe injury. When researchers repeatedly jolted a rat's damaged spinal cord at the precise moment that it tried to move a paralyzed limb, its nervous system developed new neural pathways that detoured around the site of injury in the spine. Researchers don't think it grew new neurons, but think instead that new connections formed between surviving neurons. -
Software Takes On School Science Tests In Search For Common Sense
holy_calamity writes: Making software take school tests designed for human kids can help the quest for machines with common sense, says researchers at the Allen Institute for Artificial Intelligence. They've made software called Aristo that scores 75 percent on the multiple choice questions that make up most of New York State's 4th grade science exam. The researchers are urging other researchers to pit their best software against school tests, too, to provide a way to benchmark progress and spur competition. -
How Artificial Intelligence Can Fight Air Pollution In China
An anonymous reader writes: IBM is testing a new way to help fix Beijing's air pollution problem with artificial intelligence. Like many other cities across the country, the capital is surrounded by many coal burning factories. However, the air quality on a day-to-day basis can vary because of a number of reasons like industrial activity, traffic congestion, and the weather. IBM is testing a computer system capable of learning to predict the severity of air pollution several days in advance using large quantities of data from several different models. "We have built a prototype system which is able to generate high-resolution air quality forecasts, 72 hours ahead of time," says Xiaowei Shen, director of IBM Research China. "Our researchers are currently expanding the capability of the system to provide medium- and long-term (up to 10 days ahead) as well as pollutant source tracking, 'what-if' scenario analysis, and decision support on emission reduction actions." -
Another Step In Quantum Computing: A Functional Interconnect
New submitter Gennerik writes: According to a recent article in the MIT Technology Review, a team of international physicists have been able to create a quantum computing interconnect. The interconnect, which is used to connect separate silicon photonic chips, has the important feature of preserving entanglement. This marks a vital step in creating quantum computers that don't have to work in isolation. According to the article, the trick that The trick that [University of Bristol Researcher Mark Thomson] and pals have perfected is to convert the path-entanglement into a different kind of entanglement, in this case involving polarization. They do this by allowing the path-entangled photons to interfere with newly created photons in a way that causes them to become polarized. This also entangles the newly created photons, which pass into the optical fiber and travel to the second silicon photonic chip. -
How Long Until We Have a Home Robot That Lives Up To the Hype?
moon_unit2 writes: You may have heard of "personal robots" such as Jibo, Buddy, and Pepper. One journalist recently met one of these home bots and found the reality less dazzling than the promotional videos. Whereas the Indiegogo clips of Buddy show the robot waking people up and helping with cooking, the current prototype can only perform a few canned tasks, and it struggles with natural language processing and vision. As the writer notes, the final version may be a lot more sophisticated, but it's hard to believe that real home helpers are just around the corner. -
Intel Promises 'Optane' SSDs Based On Technology Faster Than Flash In 2016
holy_calamity writes: Intel today announced that it will introduce SSDs based on a new non-volatile memory that is significantly faster than flash in 2016. A prototype was shown operating at around seven times as fast as a high-end SSD available today. Intel's new 3D Xpoint memory technology was developed in collaboration with Micron and is said to be capable of operating as much as 1000 times faster than flash. Scant details have been released, but the technology has similarities with the RRAM and memristor technologies being persued by other companies. -
Tech's Enduring Great-Man Myth
An anonymous reader writes: Did Steve Jobs deserve his reputation as a brilliant inventor? Since Jobs's death in 2011, Elon Musk has been thrust into the spotlight as a man who can shake the pillars of tech. Does he deserve that reputation? MIT's Technology Review argues that media and the industry have a habit of making legends out of notable leaders, while failing to acknowledge all the support that allowed them to execute their ideas. From the article: "Musk's success would not have been possible without, among other things, government funding for basic research and subsidies for electric cars and solar panels. Above all, he has benefited from a long series of innovations in batteries, solar cells, and space travel." While it may be fun to compare him to Iron Man, the myth has its perils: "The problem with such portrayals is not merely that they are inaccurate and unfair to the many contributors to new technologies. By warping the popular understanding of how technologies develop, great-man myths threaten to undermine the structure that is actually necessary for future innovations." -
Microsoft Creates a Quantum Computer-Proof Version of TLS Encryption Protocol
holy_calamity writes: When (or if) quantum computers become practical they will make existing forms of encryption useless. But now researchers at Microsoft say they have made a quantum-proof version of the TLS encryption protocol we could use to keep online data secure in the quantum computing era. It is based on a mathematical problem very difficult for both conventional and quantum computers to crack. That tougher math means data moved about 20 percent slower in comparisons with conventional TLS, but Microsoft says the design could be practical if properly tuned up for use in the real world. -
Why So Many Robots Struggled With the DARPA Challenge
stowie writes: The DARPA Robots Challenge concluded recently, and three teams were given prizes for completing all the tasks. The other robots in the competition struggled — not only were they unable to complete the required tasks, many of them were unable to even stay standing the entire time. So why did these robots have such a hard time? "DARPA deliberately degraded communications (low bandwidth, high latency, intermittent connection) during the challenge to truly see how a human-robot team could collaborate in a Fukushima-type disaster. And there was no standard set for how a human-robot interface would work. So, some worked better than others. The winning DRC-Hubo robot used custom software designed by Team KAIST that was engineered to perform in an environment with low bandwidth. It also used the Xenomai real-time operating system for Linux and a customized motion control framework. The second-place finisher, Team IHMC, used a sliding scale of autonomy that allowed a human operator to take control when the robot seemed stumped or if the robot knew it would run into problems." If nothing else, the competition's true legacy may lie in educating the public on the realistic capabilities of high-tech robots. -
Researchers Power a Security Camera With Wi-Fi Signals
Kristine Lofgren writes: Nikola Tesla dreamed of a world full of free, wireless power. While he never accomplished that dream during his lifetime, researchers at the University of Washington are doing their part to make it a reality with a breakthrough in wi-fi powered electronics. Dubbed PoWi-Fi, the team led by Vamsi Talla were able to recharge and maintain consistent low-level power over a number of different devices at distances of up to 28 feet. -
New Chips Could Bring Deep Learning Algorithms To Your Smartphone
catchblue22 writes: At the Embedded Vision Summit, a company called Synopsys, showed off a new image-processor core tailored for deep learning. It is expected to be added to chips that power smartphones, cameras, and cars. Synopsys showed a demo in which the new design recognized speed-limit signs in footage from a car. The company also presented results from using the chip to run a deep-learning network trained to recognize faces. A spokesperson said that it didn't hit the accuracy levels of the best research results, which have been achieved on powerful computers, but it came pretty close. "For applications like video surveillance it performs very well," he said. Being able to use deep learning on mobile chips will be vital to helping robots navigate and interact with the world, he said, and to efforts to develop autonomous cars. -
Baidu's Supercomputer Beats Google At Image Recognition
catchblue22 writes: Using the ImageNet object classification benchmark, Baidu’s Minwa supercomputer scanned more than 1 million images and taught itself to sort them into about 1,000 categories and achieved an image identification error rate of just 4.58 percent, beating humans, Microsoft and Google. Google's system scored a 95.2% and Microsoft's, a 95.06%, Baidu said. “Our company is now leading the race in computer intelligence,” said Ren Wu, a Baidu scientist working on the project. “I think this is the fastest supercomputer dedicated to deep learning,” he said. “We have great power in our hands—much greater than our competitors.” -
Apple's Plans For Your DNA
An anonymous reader writes: MIT's Technology Review breaks news that Apple is working with scientists to create apps that collect and evaluate users' DNA. "The apps are based on ResearchKit, a software platform Apple introduced in March that helps hospitals or scientists run medical studies on iPhones by collecting data from the devices' sensors or through surveys." A source says Apple's plan is to enable users to easily share their DNA information with medical workers and researchers performing studies. "To join one of the studies, a person would agree to have a gene test carried out—for instance, by returning a "spit kit" to a laboratory approved by Apple. The first such labs are said to be the advanced gene-sequencing centers operated by UCSF and Mount Sinai." -
Researchers Detect Android Apps That Connect to User Tracking and Ad Sites
An anonymous reader writes: A group of European researchers has developed software that tracks the URLs to which cellphone apps connect. After downloading 2,000+ free apps from Google Play, they indexed all the sites those apps connected to, and compared them to a list of known advertising and user tracking sites. "In total, the apps connect to a mind-boggling 250,000 different URLs across almost 2,000 top level domains. And while most attempt to connect to just a handful of ad and tracking sites, some are much more prolific. Vigneri and co give as an example "Music Volume Eq," an app designed to control volume, a task that does not require a connection to any external urls. And yet the app makes many connections. 'We find the app Music Volume EQ connects to almost 2,000 distinct URLs,' they say. [Another major offender] is an app called Eurosport Player which connects to 810 different user tracking sites." The researchers plan to publish their software for users to try out on Google Play soon. -
Researchers Mount Cyberattacks Against Surgery Robot
An anonymous reader writes: A group of researchers from University of Washington have tested the security of a teleoperated robotic surgery system created by their colleagues, and have found it severely lacking. "Teleoperated surgical robots will be expected to use a combination of existing publicly available networks and temporary ad-hoc wireless and satellite networks to send video, audio and other sensory information between surgeons and remote robots. It is envisioned these systems will be used to provide immediate medical relief in under-developed rural terrains, areas of natural and human-caused disasters, and in battlefield scenarios," the researchers noted, and asked: "But what if these robotic systems are attacked and compromised?" -
Robot Workers' Real Draw: Reducing Dependence on Human Workers
HughPickens.com writes: Zeynep Tufekci writes in an op-ed at the NY Times that machines are getting better than humans at figuring out who to hire, who's in a mood to pay a little more for that sweater, and who needs a coupon to nudge them toward a sale. It turns out most of what we think of as expertise, knowledge and intuition is being deconstructed and recreated as an algorithmic competency, fueled by big data. "Machines aren't used because they perform some tasks that much better than humans, but because, in many cases, they do a "good enough" job while also being cheaper, more predictable and easier to control than quirky, pesky humans," writes Tufekci. "Technology in the workplace is as much about power and control as it is about productivity and efficiency."
According to Tufekci technology is being used in many workplaces: to reduce the power of humans, and employers' dependency on them, whether by replacing, displacing or surveilling them. Optimists insist that we've been here before, during the Industrial Revolution, when machinery replaced manual labor, and all we need is a little more education and better skills. Tufekci points out that one historical example is no guarantee of future events. "Confronting the threat posed by machines, and the way in which the great data harvest has made them ever more able to compete with human workers, must be about our priorities," concludes Tufekci. "This problem is not us versus the machines, but between us, as humans, and how we value one another." -
Researchers Developing An Algorithm That Can Detect Internet Trolls
An anonymous reader writes Researchers at Cornell University claim to be able to identify a forum or comment-thread troll within the first ten posts after the user joins with more than 80% accuracy, leading the way to the possibility of methods to automatically ban persistently anti-social posters. The study observed 10,000 new users at cnn.com, breitbart.com and ign.com, and characterizes an FBU (Future Banned User) as entering a new community with below-average literacy or communications skill, and that the low standard is likely to drop shortly before a permanent ban. It also observes that higher rates of community intolerance are likely to foster the anti-social behavior and speed the ban. -
California Looks To the Sea For a Drink of Water
HughPickens.com writes Justin Gillis writes in the NYT that as drought strikes California, residents can't help noticing the substantial reservoir of untapped water lapping at their shores — 187 quintillion gallons of it, more or less, shimmering invitingly in the sun. Once dismissed as too expensive and harmful to the environment desalination is getting a second look. A $1 billion desalination plant to supply booming San Diego County is under construction and due to open as early as November, providing a major test of whether California cities will be able to resort to the ocean to solve their water woes. "It was not an easy decision to build this plant," says Mark Weston, chairman of the agency that supplies water to towns in San Diego County. "But it is turning out to be a spectacular choice. What we thought was on the expensive side 10 years ago is now affordable."
Carlsbad's product will sell for around $2,000 per acre-foot (the amount used by two five-person U.S. households per year), which is 80 percent more than the county pays for treated water from outside the area. Water bills already average about $75 a month and the new plant will drive them up by $5 or so to secure a new supply equal to about 7 or 8 percent of the county's water consumption. Critics say the plant will use a huge amount of electricity, increasing the carbon dioxide emissions that cause global warming, which further strains water supplies. And local environmental groups, which fought the plant, fear a substantial impact on sea life. "There is just a lot more that can be done on both the conservation side and the water-recycling side before you get to [desalination]," says Rick Wilson, coastal management coordinator with the environmental group Surfrider Foundation. "We feel, in a lot of cases, that we haven't really explored all of those options." -
Inexpensive Electric Cars May Arrive Sooner Than You Think
catchblue22 writes According to an article in MIT Technology Review, a new peer reviewed study suggests that battery-powered vehicles are close to being cost-effective for most people: "Electric cars may seem like a niche product that only wealthy people can afford, but a new analysis suggests that they may be close to competing with or even beating gas cars on cost. ... The authors of the new study concluded that the battery packs used by market-leading EV manufacturers like Tesla and Nissan cost as little as $300 per kilowatt-hour of energy in 2014. That's lower than the most optimistic published projections for 2015, and even below the average published projection for 2020. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. If that's true, it would push EVs across a meaningful threshold." -
Amazon Robot Contest May Accelerate Warehouse Automation
moon_unit2 writes Amazon is organizing an event to spur the development of more nimble-fingered product-packing robots. Participating teams will earn points by locating products sitting somewhere on a stack of shelves, retrieving them safely, and then packing them into cardboard shipping boxes. Robots that accidentally crush a cookie or drop a toy will have points deducted. The contest is already driving new research on robot vision and manipulation, and it may offer a way to judge progress made in the past few years in machine intelligence and dexterity. Robots capable of advanced manipulation could eventually take on many simple jobs that are still done by hand. -
Data Research Reveals When Taking a Yellow Cab Is Cheaper Than an Uber
An anonymous reader writes A team of data scientists have come up with a system to identify times when regular yellow taxis are cheaper alternatives to an Uber [in New York]. Researchers from the University of Cambridge and the University of Nanmur in Belgium have compared a broad dataset of both yellow taxi and Uber fares in New York and have discovered that for a trip costing less than $35 Uber is often the most expensive option. The data scientists were able to reach this conclusion by comparing trip and fare data for each yellow taxi ride taken in 2013 and entering it into Uber's fare query system. Prices were taken from Uber's lowest-cost service Uber X and the NYC Taxi and Limousine Commission. -
Breakthrough In Face Recognition Software
An anonymous reader writes: Face recognition software underwent a revolution in 2001 with the creation of the Viola-Jones algorithm. Now, the field looks set to dramatically improve once again: computer scientists from Stanford and Yahoo Labs have published a new, simple approach that can find faces turned at an angle and those that are partially blocked by something else. The researchers "capitalize on the advances made in recent years on a type of machine learning known as a deep convolutional neural network. The idea is to train a many-layered neural network using a vast database of annotated examples, in this case pictures of faces from many angles. To that end, Farfade and co created a database of 200,000 images that included faces at various angles and orientations and a further 20 million images without faces. They then trained their neural net in batches of 128 images over 50,000 iterations. ... What's more, their algorithm is significantly better at spotting faces when upside down, something other approaches haven't perfected." -
Nanotech Makes Steel 10x Stronger
An anonymous reader writes: A new metal-making process currently in testing at oil fields uses nano-scale plating to make metals like steel as much as ten times stronger than they would be without it. "[The process] uses an advanced form of electroplating, a process already used to make the chrome plating you might see on the engine and exhaust pipes of a motorcycle. Electroplating involves immersing a metal part in a chemical bath containing various metal ions, and then applying an electrical current to cause those ions to form a metal coating. The company uses a bath that contains more than one kind of metal ion and controls how ions are deposited by varying the electrical current. By changing the current at precise moments, it can create a layered structure, with each layer being several nanometers thick and of different composition. The final coating can be up to a centimeter thick and can greatly change the properties of the original material." -
2015 Could Be the Year of the Hospital Hack
schwit1 writes After Obamacare required hospitals to convert all health records into electronic files, those records are now very vulnerable, and experts expect hackers to target them in the coming years. From the article: "Along with vast troves of credit card information and celebrity snapshots, hackers stole a record number of medical records from U.S. health-care facilities this year. In 2015, attacks targeting health data will become even more common, according to security researchers....The cause of the uptick isn't hard to diagnose. Medical organizations across the world are switching to electronic medical records, and computer security is not always a high enough priority during the process, says Leonard. Besides that, he says, easy and fast access to medical information often trumps security." -
Using Discarded Laptop Batteries To Power Lights
mrspoonsi sends news of an IBM study (PDF) which found that discarded laptop batteries could be used to power lights in areas where there's little or no electrical grid. Of the sample IBM tested, 70% of the used batteries were able to power an LED light for more than four hours every day throughout an entire year. The concept was trialed in the Indian city of Bangalore this year. The adapted power packs are expected to prove popular with street vendors, who are not on the electric grid, as well as poor families living in slums. The IBM team created what they called an UrJar — a device that uses lithium-ion cells from the old batteries to power low-energy DC devices, such as a light. The researchers are aiming to help the approximately 400 million people in India who are off grid. -
Behind Apple's Sapphire Screen Debacle
Frankie70 (803801) writes Apple invested more than $1 billion in an effort to make sapphire one of iPhone 6's selling point. But the iPhone 6 was released without the sapphire screen. GT Advanced Technologies, the small company chosen to supply Apple with enormous quantities of cheap sapphire, declared bankruptcy a month later. Recent documents from GT's bankruptcy proceedings, and conversations with people familiar with operations at Apple and GT, provide several clues as to what went wrong. GT said that to save costs, Apple decided not to install backup power supplies, and multiple outages ruined whole batches of sapphire. The terms Apple negotiated committed GT to supplying a huge amount of sapphire, but put Apple under no obligation to buy it. In its bankruptcy documents, GT would later accuse Apple of using "bait-and-switch" tactics, and said the terms of the deal were "onerous and massively one-sided." -
Machine-Learning Algorithm Ranks the World's Most Notable Authors
HughPickens.com writes: Every year the works of thousands of authors enter the public domain, but only a small percentage of these end up being widely available. So how do organizations such as Project Gutenberg choose which works to focus on? Allen Riddell has developed an algorithm that automatically generates an independent ranking of notable authors for any given year. It is then a simple task to pick the works to focus on or to spot notable omissions from the past. Riddell's approach is to look at what kind of public domain content the world has focused on in the past and then use this as a guide to find content that people are likely to focus on in the future.
Riddell's algorithm begins with the Wikipedia entries of all authors in the English language edition (PDF)—more than a million of them. His algorithm extracts information such as the article length, article age, estimated views per day, time elapsed since last revision, and so on. This produces a "public domain ranking" of all the authors that appear on Wikipedia. For example, the author Virginia Woolf has a ranking of 1,081 out of 1,011,304 while the Italian painter Giuseppe Amisani, who died in the same year as Woolf, has a ranking of 580,363. So Riddell's new ranking clearly suggests that organizations like Project Gutenberg should focus more on digitizing Woolf's work than Amisani's. Of the individuals who died in 1965 and whose work will enter the public domain next January in many parts of the world, the new algorithm picks out TS Eliot as the most highly ranked individual. Others highly ranked include Somerset Maugham, Winston Churchill, and Malcolm X. -
Military Laser/Radio Tech Proposed As Alternative To Laying Costly Fiber Cable
An anonymous reader writes "Californian comm-tech company Aoptix is testing new laser+radio hybrid communications technology with three major U.S. internet carriers. The equipment required can be bolted onto existing infrastructure, such as cell-tower masts, and can communicate a 2gbps stream over 6.5 miles. The system was developed over 10 years at a cost of $100 million in conjunction with the Air Force Research Laboratory, and the military implementation of it is called Aoptix Enhanced Air Ground Lasercom System (EAGLS). The laser component of the technology uses a deformable mirror to correct for atmospheric distortion over the mast-hop, in real-time. The laser part of the system is backed-up by a redundant radio transmitter. The radio component has low attenuation in rainy conditions with large refracting raindrops, while the laser is more vulnerable to dense fog. The system, which features auto-stabilization to compensate for cell-tower movement and is being proposed as an alternative to the tremendous cost p/m of laying fiber cable, is being tested in Mexico and Nigeria in addition to the three ISP trials. -
fMRI Data Reveals How Many Parallel Processes Run In the Brain
New submitter xgeorgio writes: From MIT Technology Review: "The human brain carries out many tasks at the same time, but how many? Now fMRI data has revealed just how parallel gray matter is. ... Although the analysis is complex, the outcome is simple to state. Georgiou says independent component analysis reveals that about 50 independent processes are at work in human brains performing the complex visuo-motor tasks of indicating the presence of green and red boxes. However, the brain uses fewer processes when carrying out simple tasks, like visual recognition.
That's a fascinating result that has important implications for the way computer scientists should design chips intended to mimic human performance. It implies that parallelism in the brain does not occur on the level of individual neurons but on a much higher structural and functional level, and that there are about 50 of these. 'This means that, in theory, an artificial equivalent of a brain-like cognitive structure may not require a massively parallel architecture at the level of single neurons, but rather a properly designed set of limited processes that run in parallel on a much lower scale,' he concludes."

Does Watson Have the Answer To Big Blue's Uncertain Future?
HughPickens.com writes: IBM has recently delivered a string of disappointing quarters, and announced recently that it would take a multibillion-dollar hit to offload its struggling chip business. But Will Knight writes at MIT Technology Review that Watson may have the answer to IBM's uncertain future. IBM's vast research department was recently reorganized to ramp up efforts related to cognitive computing. The push began with the development of the original Watson, but has expanded to include other areas of software and hardware research aimed at helping machines provide useful insights from huge quantities of often-messy data. "We're betting billions of dollars, and a third of this division now is working on it," says John Kelly, director of IBM Research, said of cognitive computing, a term the company uses to refer to artificial intelligence techniques related to Watson. The hope is that the Watson Business Group, a division aimed making its Jeopardy!-winning cognitive computing application more of a commercial success, will be able to answer more complicated questions in all sorts of industries, including health care, financial investment, and oil discovery; and that it will help IBM build a lucrative new computer-driven consulting business.
But Watson is still a work in progress. Some companies and researchers testing Watson systems have reported difficulties in adapting the technology to work with their data sets. "It's not taking off as quickly as they would like," says Robert Austin. "This is one of those areas where turning demos into real business value depends on the devils in the details. I think there's a bold new world coming, but not as fast as some people think." IBM needs software developers to embrace its vision and build services and apps that use its cognitive computing technology. In May of this year it announced that seven universities would offer computer science classes in cognitive computing and last month IBM revealed a list of partners that have developed applications by tapping into application programming interfaces that access versions of Watson running in the cloud. Big Blue said it will invest $1 billion into the Watson division including $100 million to fund startups developing cognitive apps. "I very much admire the end goal," says Boris Katz, adding that business pressures could encourage IBM's researchers to move more quickly than they would like. "If the management is patient, they will really go far." -
Revitalizing Medical Imaging With Ultrasound-On-a-Chip
catchblue22 writes: MIT Technology Review has an article about a device being developed by Butterfly Network that aims to make medical imaging dirt cheap. From the article: "Butterfly's patent applications describe its aim as building compact, versatile new ultrasound scanners that can create 3-D images in real time. Hold it up to a person's chest, and you would look through 'what appears to be a window' into the body, according to the documents. ... Most ultrasound machines use small piezoelectric crystals or ceramics to generate and receive sound waves. But these have to be carefully wired together, then attached via cables to a separate box to process the signals. Anyone who can integrate ultrasound elements directly onto a computer chip could manufacture them cheaply in large batches, and more easily create the type of arrays needed to produce 3-D images." -
Isaac Asimov: How Do People Get New Ideas?
HughPickens.com writes: Arthur Obermayer, a friend of the Isaac Asimov, writes that he recently rediscovered an unpublished essay by Asimov written in 1959 while cleaning out some old files. Obermayer says it is "as broadly relevant today as when he wrote it. It describes not only the creative process and the nature of creative people but also the kind of environment that promotes creativity." Here's an excerpt from Asimov's essay, which is well worth reading in its entirety:
"A person willing to fly in the face of reason, authority, and common sense must be a person of considerable self-assurance. Since he occurs only rarely, he must seem eccentric (in at least that respect) to the rest of us. A person eccentric in one respect is often eccentric in others. Probably more inhibiting than anything else is a feeling of responsibility. The great ideas of the ages have come from people who weren't paid to have great ideas, but were paid to be teachers or patent clerks or petty officials, or were not paid at all. The great ideas came as side issues." A couple more quotes:
"My feeling is that as far as creativity is concerned, isolation is required. The creative person is, in any case, continually working at it. His mind is shuffling his information at all times, even when he is not conscious of it. The presence of others can only inhibit this process, since creation is embarrassing. For every new good idea you have, there are a hundred, ten thousand foolish ones, which you naturally do not care to display."
"Presumably, the process of creativity, whatever it is, is essentially the same in all its branches and varieties, so that the evolution of a new art form, a new gadget, a new scientific principle, all involve common factors. It is only afterward that a new idea seems reasonable. What is needed is not only people with a good background in a particular field, but also people capable of making a connection between item 1 and item 2 which might not ordinarily seem connected. To begin with, it usually seems unreasonable. It seems the height of unreason to suppose the earth was round instead of flat, or that it moved instead of the sun, or that objects required a force to stop them when in motion, instead of a force to keep them moving, and so on." -
An Air Traffic Control System For Drones
An anonymous reader writes: Personal drones are become more popular, and many companies are trying to figure out ways to incorporate them into their business. So what do we do in 10 years, when the skies are full of small, autonomous vehicles? NASA and a startup called Airware are working on a solution: air traffic control for drones. "The first prototype to be developed under NASA's project will be an Internet-based system. Drone operators will file flight plans for approval. The system will use what it knows about other drone flights, weather forecasts, and physical obstacles such as radio masts to give the go-ahead. Later phases of the project will build more sophisticated systems that can actively manage drone traffic by sending out commands to drones in flight. That could mean directing them to spread out when craft from multiple operators are flying in the same area, or taking action when something goes wrong, such as a drone losing contact with its operator, says Jonathan Downey, CEO of Airware. If a drone strayed out of its approved area, for example, the system might automatically send a command that made it return to its assigned area, or land immediately." -
Microsoft's Quantum Mechanics
New submitter catchblue22 writes MIT Technology Review has an excellent article summarizing the current state of quantum computing. It focuses on the efforts of Microsoft and Alcatel-Lucent's Bell Labs to build stable qubits over the past few years. "In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana fermion, finally confirming a prediction made in 1937. It was an advance seemingly unrelated to the challenges of selling office productivity software or competing with Amazon in cloud computing, but Craig Mundie, then heading Microsoft's technology and research strategy, was delighted. The abstruse discovery — partly underwritten by Microsoft — was crucial to a project at the company aimed at making it possible to build immensely powerful computers that crunch data using quantum physics. "It was a pivotal moment," says Mundie. "This research was guiding us toward a way of realizing one of these systems." -
Michigan Builds Driverless Town For Testing Autonomous Cars
HughPickens.com writes Highway driving, which is less complex than city driving, has proved easy enough for self-driving cars, but busy downtown streets—where cars and pedestrians jockey for space and behave in confusing and surprising ways—are more problematic. Now Will Knight reports that Michigan's Department of Transportation and 13 companies involved with developing automated driving technology are constructing a 30-acre, $6.5 million driverless town near Ann Arbor to test self-driving cars in an urban environment. Complex intersections, confusing lane markings, and busy construction crews will be used to gauge the aptitude of the latest automotive sensors and driving algorithms and mechanical pedestrians will even leap into the road from between parked cars so researchers can see if they trip up onboard safety systems. "I think it's a great idea," says John Leonard, a professor at MIT who led the development of a self-driving vehicle for a challenge run by DARPA in 2007. "It is important for us to try to collect statistically meaningful data about the performance of self-driving cars. Repeated operations—even in a small-scale environment—can yield valuable data sets for testing and evaluating new algorithms." The testing facility is part of broader work by the University of Michigan's Mobility Transformation Facility that will include putting up to 20,000 vehicles on southeastern Michigan roads. By 2021, Ann Arbor could become the first American city with a shared fleet of networked, driverless vehicles. "Ann Arbor will be seen as the leader in 21st century mobility," says Peter Sweatman, director of the U-M Transportation Research Institute. "We want to demonstrate fully driverless vehicles operating within the whole infrastructure of the city within an eight-year timeline and to show that these can be safe, effective and commercially successful." -

LTE Upgrade Will Let Phones Connect To Nearby Devices Without Towers
An anonymous reader sends this excerpt from MIT's Technology Review: A new feature being added to the LTE protocol that smartphones use to communicate with cellular towers will make it possible to bypass those towers altogether. Phones will be able to "talk" directly to other mobile devices and to beacons located in shops and other businesses. Known as LTE Direct, the wireless technology has a range of up to 500 meters, far more than either Wi-Fi or Bluetooth. It is included in update to the LTE standard slated for approval this year, and devices capable of LTE Direct could appear as soon as late 2015. ... Researchers are, for example, testing LTE Direct as a way to allow smartphones to automatically discover nearby people, businesses, and other information. -
The Challenges and Threats of Automated Lip Reading
An anonymous reader writes: Speech recognition has gotten pretty good over the past several years. it's reliable enough to be ubiquitous in our mobile devices. But now we have an interesting, related dilemma: should we develop algorithms that can lip read? It's a more challenging problem, to be sure. Sounds can be translated directly into words, but deriving meaning out of the movement of a person's face is much more complex. "During speech, the mouth forms between 10 and 14 different shapes, known as visemes. By contrast, speech contains around 50 individual sounds known as phonemes. So a single viseme can represent several different phonemes. And therein lies the problem. A sequence of visemes cannot usually be associated with a unique word or sequence of words. Instead, a sequence of visemes can have several different solutions." Beyond the computational aspect, we also need to decide, as a society, if this is a technology that should exist. The privacy implications extend beyond that of simple voice recognition. -
Hidden Obstacles For Google's Self-Driving Cars
Paul Fernhout writes: Lee Gomes at MIT's Technology Review wrote an article on the current limits of Google self-driving car technology: "Would you buy a self-driving car that couldn't drive itself in 99 percent of the country? Or that knew nearly nothing about parking, couldn't be taken out in snow or heavy rain, and would drive straight over a gaping pothole? If your answer is yes, then check out the Google Self-Driving Car, model year 2014. Google often leaves the impression that, as a Google executive once wrote, the cars can 'drive anywhere a car can legally drive.' However, that's true only if intricate preparations have been made beforehand, with the car's exact route, including driveways, extensively mapped. Data from multiple passes by a special sensor vehicle must later be pored over, meter by meter, by both computers and humans. It's vastly more effort than what's needed for Google Maps. ... Among other unsolved problems, Google has yet to drive in snow, and Urmson says safety concerns preclude testing during heavy rains. Nor has it tackled big, open parking lots or multilevel garages. ... Pedestrians are detected simply as moving, column-shaped blurs of pixels — meaning, Urmson agrees, that the car wouldn't be able to spot a police officer at the side of the road frantically waving for traffic to stop." Paul continues, 'A deeper issue I wrote about in 2001 is whether such software and data will be FOSS or proprietary? As I wrote there: "We are about to see the emergence of companies licensing that publicly funded software and selling modified versions of such software as proprietary products. There will eventually be hundreds or thousands of paid automotive software engineers working on such software no matter how it is funded, because there will be great value in having such self-driving vehicles given the result of America's horrendous urban planning policies leaving the car as generally the most efficient means of transport in the suburb. The question is, will the results of the work be open for inspection and contribution by the public? Essentially, will those engineers and their employers be "owners" of the software, or will they instead be "stewards" of a larger free and open community development process?"' -
Study: Social Networks Have Negative Effect On Individual Welfare
An anonymous reader writes: A study of 50,000 people in Italy has found the impact of social networking on individual welfare to be "significantly negative." The researchers found that improvements in self-reported well-being occurred when online networking led to face-to-face interactions, but this effect was overwhelmed by the perceived losses in well-being (PDF) generated by interaction strictly through social networks. The researchers "highlight the role of discrimination and hate speech on social media which they say play a significant role in trust and well-being. Better moderation could significantly improve the well-being of the people who use social networks, they conclude." -
Wireless Contraception
Kittenman writes: The BBC is carrying information on a type of contraception (funded in part by Bill Gates) that takes the form of a microchip, inserted under the skin. The chip releases contraceptive hormones to the body until wirelessly advised not to do so. This device has several interesting applications and issues associated with it. The researchers are already working on making the device secure against unauthorized transmissions. There's also the issue of making it easier for governments to control population levels. The chip will be available from 2018. This correspondent will watch the issues with interest. -
Here Comes the Panopticon: Insurance Companies
New submitter jbmartin6 writes: The Panopticon may be coming, but perhaps not how we think. Instead of a massive government surveillance program, we might end up subjected to ubiquitous monitoring to save on our insurance premiums. The "internet of things (you can't get away from)" makes this more and more possible. Here a company saved money on its health insurance premiums by distributing Fitbits and an online service to enable reporting fitness gains back to the insurance company. We've already seen the stories on using black boxes to monitor drivers. There is even an insurance company named Panoptic! Heck, why not a premium hike for owners of this or that "aggressiveness gene"? What if in the future we got a quick "+50 cents" tweet for every scoop of ice cream? I suppose the natural stopping point might be the balance between an individual's willingness to be monitored and the desire to reduce insurance premiums. -
Intelligent Thimble Could Replace the Mouse In 3D Virtual Reality Worlds
New submitter anguyen8 (3736553) writes with news of an interesting experimental spatial input device. From the article: "The mouse is a hugely useful device but it is also a two-dimensional one. But what of the three-dimensional world and the long-standing, but growing, promise of virtual reality. What kind of device will take the place of the mouse when we begin to interact in three-dimensions? Anh Nguyen and Amy Banic ... have created an intelligent thimble that can sense its position accurately in three-dimensions and respond to a set of pre-programmed gestures that allow the user to interact with objects in a virtual three-dimensional world. ... The result is the 3DTouch, a thimble-like device that sits on the end of a finger, equipped with a 3D accelerometer, a 3D magnetometer, and 3D gyroscope. That allows the data from each sensor to be compared and combined to produce a far more precise estimate of orientation than a single measurement alone. In addition, the 3DTouch has an optical flow sensor that measures the movement of the device against a two-dimensional surface, exactly like that inside an ordinary mouse." The prototype is wired up to an Arduino Uno, with a program on the host machine polling the device and converting the data into input events. A video of it in action is below the fold, a pre-print of the research paper is on arxiv, and a series of weblog entries explain some of the development.
