The use of the word "predict" is for ease-of-understanding for the business market and those not familiar with machine learning. Many of the comments here are getting lost in that word. The algorithms behind the API are most likely the same basic ones that have been around for a long time: naive bayes, svm, knn, etc. The actual novelty of this service is that it puts these methods in easy reach for people who otherwise wouldn't know where to start looking, or wouldn't know how to use one of the many available libraries already around, or much less implement something themselves.

yep, that's why I said "at the moment". buzz feels pretty isolated right now, we'll see how/if it opens up.

Two Scoops of Buzz
·
· Score: 2, Insightful
Not 'closed' in that sense. Closed as in finite (in comparison to the other services where anyone with any email address can use). To be able to use buzz, one needs to sign up for another email account, something not many people will do easily.
At the moment, there are a number of things holding buzz back from widespread usage:
* buzz has a userbase/ceiling/: the number of gmail users; the userbase may be large but it's closed and entry is a large hurdle for many
* complicating the adoption is the number of those gmail users whose friends also use gmail and would be likely to use buzz, lowering the actual ceiling further
* when people see that not many of their friends are using it, but are/have been using other services, that makes buzz adoption difficult
there are advantages to buzz of course (mobile/geo-loc/post length/etc), but the question remains whether those advantages will eventually outweigh the challenges to more widespread adoption.
Those comparative shots of the Carina Nebula are showing the difference between "visible light" and infrared, not colors. The visible light image has false color.
Exactly, it's really a combination of engineering and fortune. If not for the fortunate wind storms these rovers would have frozen long ago, and if not for the good engineering, even with clean solar panels, the rovers would have broken/quit before now.
Semantic processing systems like this (it's not something new) aren't usually able to determine correctness. The truth of a statement is assumed and the best these NLP engines can do at the moment is identify conflicts and maybe use some reputation metrics to assign a veracity rating to a particular statement, or notify the user that there are differing conclusions. These systems are just really, like the summary states, "information extraction" systems. Just as a regular search engine will return you the results from the data set, that's what these types of semantic extraction engines usually do, except the data is processed in a semantically-organized way so that you can query with semantics/natural language constraints instead of just keywords and boolean constraints.
There are some that incorporate some intention or opinion polarity detection, but even those are not capable to sorting "truth" versus "conspiracy".
I don't think current QA systems would be confused by that question, actually. In the simplest case of just keyword searching for the appropriate passage, the occurence of "author" with a type of town called "hamlet" will be far smaller than "author" with the play name "Hamlet". Not to mention some systems will pre-mark "Hamlet" as some category precluding a town (like "play"). This lack of co-occurrence also assists statistical methods when learning.
The rhyming and puns will be the more difficult tasks to handle.
Parsing of the questions is the really difficult part of QA. However, the usage of category names isn't something brand new in the field. See the NIST TRECQuestion Answering competition. The lastcouple of years' challenges involved a group of questions referencing a "target" and/or the previous question or previous answer to correctly formulate the current answer.
Example: TARGET: John William King convicted of murder Q1: How many non-white members of the jury were there? Q3: Where was the trial held? Q4: When was King convicted? Q5: Who was the victim of the murder?
Sorry, wrong stage. From stage 1: "To keep the dynamic pressure on the vehicle below a specified level, on the order of 580 pounds per square foot (max q), the main engines are throttled down at approximately 26 seconds and throttled back up at approximately 60 seconds."
At what point do these stripped-down netbooks begin competing directly with large screen, wi-fi/wan-enabled cell phones that can be used as a 'browser in a box' with office document reading/editing, games, email, IM, plus being a cell phone?
Reaching the levels of $200 and below are right at subsidized smartphone levels. With new chips like Qualcomm's 1Ghz snapdragon now in use in a phone with a 4.1", 480x800 touchscreen, what makes a netbook at these levels competitive? Would screen size alone win out over features?
Players would have the option for easier communication at a risk, or would have to find some other way to communicate which would carry it's own advantages and disadvantages, which I think is a reasonable disruption in modern gameplay and not one I'm so sure would annoy players so much.
Plus, methods like true, range-based "whispering" could be useful, and would also carry with it some interesting risk (i.e., the intended person wasn't close enough to hear). The fact that a particular AI might only understand one or a handful of languages seems fine to me.
I'm sure others have had similar ideas, it's just one that has interested me for a while.
As an NLP person, what I would love to see/develop is AI that "listens" to the players. Take for example a game like WoW or Halo where the players are chatting publicly (text is easier than speech) with each other about their next motion or attack or defense moves. If the AI was within "hearing" range, it could pick up on that public chatter and if possible, decide to counter in someway or ignore it as if it was diversionary or irrelevant (or simply misunderstood).
Additionally, what failed was not the parachute system destined for the actual mission, but instead the parachutes that are used to stabilize the capsule away from the delivery craft so that the real system can be accurately tested.
The test didn't fail, the set-up for the test failed.
The USSR "broke up" as a single entity, but with the major controlling constituent continuing to exist, not "erased" as you said. Plus that break-up had a profound affect on the world, no simple 'carrying on' as you said, as if nothing had happened - there were large effects. Explain again how it's automatically advantageous for the entire rest of the world if the 2nd largest economy collapses and disappears, as you are hoping.
They haven't sold cars in Canada in 15+ years either and haven't bothered to re-enter there, what does that mean? And I don't think anyone really believes that any country can just "be erased tomorrow and the world would carry on", despite whatever delusions you might have.

That query (albert einstein's birthday) worked when I tried it just now:

Apply this patch to see if the machine is infected by some seemingly-unrelated rootkit.

Additionally, semantic extraction output, like named entities and semantic relations, are useful for many other applications.

So, we just need easy break-away wings, right? Problem solved. :P

don't they have to power down a little as they break the sound barrier?

It would be an interesting experiment at least.
You have to see the orbital progression to get over the thought that it's just another speck of light noise. Here is a larger image showing the position of the planet from 2004 and 2006. Also, here is the url for the release showing the image of HR 8799 with its 3 planets.
Additionally, what failed was not the parachute system destined for the actual mission, but instead the parachutes that are used to stabilize the capsule away from the delivery craft so that the real system can be accurately tested. The test didn't fail, the set-up for the test failed.
So -88 C would become something more like 100 E
Or "212 Q".
