Strong AI and the Imminent Revolution In Robotics

An anonymous reader writes "Google director of research Peter Norvig and AI pioneer Judea Pearl give their view on the prospects of developing a strong AI and how progress in the field is about to usher in a new age of household robotics to rival the explosion of home computing in the 1980s. Norvig says, 'In terms of robotics we’re probably where the world of PCs were in the early 1970s, where you could buy a PC kit and if you were an enthusiast you could have a lot of fun with that. But it wasn’t a worthwhile investment for the average person. There wasn’t enough you could do that was useful. Within a decade that changed, your grandmother needed word processing or email and we rapidly went from a very small number of hobbyists to pervasive technology throughout society in one or two decades. I expect a similar sort of timescale for robotic technology to take off, starting roughly now.' Pearl thinks that once breakthroughs are made in handling uncertainty, AIs will quickly gain 'a far greater understanding of context, for instance providing with the next generation of virtual assistants with the ability to recognise speech in noisy environments and to understand how the position of a phrase in a sentence can change its meaning.'"

    Oh, of course. But pretending that these "breakthroughs in handling uncertainty" are just a minor stumbling block is somewhat silly. These are some of the hardest problems in maths right now, and there are no easy solutions on the horizon.

      Mod parent up.

      I'm working in that field and know Pearl's work very well. The problem with uncertainty and current framework is the complexity. Probability theory, possibility measures, ranking theory, plausibility measures, Dempster-Shafer and all these slight variations of the same theme are altogether computationally intractable. Strongly heuristic shortcuts based on implausible assumptions are used (like stipulating independence between random variables for purely technical reasons), and much better ones need to be developed. Human cognition takes amazing shortcuts and AI methods are much too combinatorial in contrast to that.

      Moreover, the problem of knowledge representation is still not solved adequately. Yes, there are a few large ontologies like Cyc, but they do not suffice. Basically, a lot of tools are there, but they are disconnected and there is no unifying framework or representation at all. To give you an example from NLP, the kind of tools used by computer scientists (e.g. description logic, event calculus) are practically worthless for doing real-world semantics, and of course logic has the same combinatorial complexity issues.

      Breakthroughs will come by combining symbolic AI with connectionist and geometric representations, but only few people work on that (e.g. Smolensky), the math is complicated and not what your average AI/CS guy or computational linguist can handle.

      I think what Norvig should have said is that robots with convincible, but ultimately non-intelligent soft AI will enter the consumer market within the next few decades - which is true, but something else entirely.

    I think not... It's not even mentioned in the article See http://en.wikipedia.org/wiki/Frame_problem or an illustation: "The philosopher Daniel Dennett asks us to imagine a robot designed to fetch a spare battery from a room that also contained a time bomb. Version 1 saw that the battery was on a wagon and that if it pulled the wagon out of the room, the battery would come with it. Unfortunately, the bomb was also on the wagon, and the robot failed to deduce that pulling the wagon out brought the bomb out, too. Version 2 was programmed to consider all the side effects of its actions. It had just finished computing that pulling the wagon would not change the color of the room's walls and was proving that the wheels would turn more revolutions than there are wheels on the wagon, when the bomb went off. Version 3 was programmed to distinguish between relevant implications and irrelevant ones. It sat there cranking out millions of implications and putting all the relevant ones on a list of facts to consider and all the irrelevant ones on a list of facts to ignore, as the bomb ticked away."

    My new automatic washing machine is an extremely useful robot, even though it does not have legs or hands.

    There is only embedded intelligence. A pure intelligence does not even exist and cannot exist.

    Why built an AI, which drives a car, if it is quite possible to build an underground transportation network and automate it with AI. This robust technology already exists.

    It is easier to send an AI robot to another planet than to a local supermarket. And the problems are not mathematical, but social. The AI is already here and it is bigger than the current society's setup. The social setup and the infrastructure of society are to be changed in order to use it.

      So in plain English instead of making an AI more capable of dealing with greater complexity (like say animals), you artificially constrain the problem set till you get something that present systems (don't need to be AI) can handle then?

    With nobody buying (being sacked, can't afford), what's the point of producing? Everything would be relatively too expensive no matter how absolutely cheap.

    This is a problem that has hit a number of slave-owning societies and is currently a problem for China. An imbalance between production and consumption is unsustainable, irrespective of the direction. It was also one of the causes of the US civil war: the south was production-heavy, which was making it hard for workers in the north to compete with cheap imports, which the south needed to keep supplying because they didn't have a large enough local consumer base.

    Most people who post on Slashdot probably can, as long as you're willing to accept a lower income than you would if you worked full time. I did for several years. I made enough to live comfortably, but not extravagantly, and had a very high quality of living. I'm now 'working' full time back in academia, because now I get paid to work on things I was doing as a hobby before. The standard of living for someone with the same inflation-adjusted income as me now is far higher than when my parents were my age.

    Of course, AI robots by themselves do not solve the problem of resource scarcity.

    Asteroids do.

    And people will continue to grow exponentially

    Don't worry, they don't and aren't.

    so on a fixed earth, you'll always reach a point where not everybody gets a basic standard of living.

    Its quite doable. And if you look at population trends in societies nearing post scarcity status, like Western Europe, it becomes clear that the best way to head off any such hypothesised difficulties is to provide a decent standard of living to as many people as possible as quickly as possible.

    You think the South in the 1850s was some hive of industry selling all manner of goods to the North?

    The South was agrarian (cotton and tobacco and stuff - you know, plantations, as in every depiction of the Old South ever, not factories) which it mostly sold abroad, not to the North. The North was where all the factory production was, which is why it was able to outproduce the South in things like artillery and rifles when the war started. Seriously, at least open a history textbook before randomly making up stuff like this.

  14. Robotics is getting there. Money works now. by Animats · · Score: 4, Interesting

    Robots are starting to work in unstructured situations. I was there at the moment when this was recognized - the 2005 DARPA Grand Challenge at the California Motor Speedway in Fontana, CA. That's when everything changed.

    The 2004 Grand Challenge, remember, was a pathetic joke. No vehicle got further than 7 miles, and that was CMU's. The CMU approach at the time wasn't even really autonomous. Entrants got the route on a CD an hour or so before the start. CMU had imagery of the whole area and tried to plan obstacle avoidance manually just before the start, using a huge team of people in a semitrailer full of workstations. Didn't work; the DoD people in charge had moved some obstacles during the night. And that was the best result. One vehicle came out of the gate, turned hard, and ran back into the starting gate. One flipped over. The big Oskosh entry demolished a SUV parked as an obstacle to be avoided. The whole thing was embarrassing.

    DARPA was very displeased with the performance by the universities that had long been receiving DARPA funding for robotics. It was quietly made clear to some major CS departments that their performance had to improve or funding would be cut off. That's why entire CS departments were suddenly devoted to the DARPA Grand Challenge in 2005.

    In 2005, things were completely different. Everybody who got that far had already been through an elimination, and every vehicle at the 2005 challenge was better than any of the 2004 entries. There was considerable press coverage, and at first, the press treated it as a joke. But suddenly there were over 20 vehicles running around autonomously, and they weren't crashing into stuff. When multiple vehicles finished the course, it was viewed as a triumph.

    Finally, the state of the art had reached the point that money and determination would get problems solved. That wasn't true in the 1980s. NASA threw over $100 million at the Flight Telerobotic Servicer project, and got nothing that worked.

    Now check out the DARPA Humanoid Challenge. (There's much dreck about this on blogs and in the popular press. Read the DARPA announcement instead.) They have an approach that's likely to work, and demand simulated demos (in their simulator) in 9 months, with demos on real hardware in 18 months. I personally think they'll get something able to do most of the mobility tasks and some of the manipulation tasks in that time. Useful humanoid robots will be a lot closer in two years.

    Price will still be a problem. But not an unsolveable one. These things could be brought down to the price of an SUV, if not lower, through production economies alone. The parts count is probably lower than that for an SUV.
