'Jeopardy!' To Pit Humans Against IBM Machine 164

digitaldc writes "The game show Jeopardy! will pit man versus machine this winter in a competition that will show how successful scientists are in creating a computer that can mimic human intelligence. Two of the venerable game show's most successful champions — Ken Jennings and Brad Rutter — will play two games against 'Watson,' a computer program developed by IBM's artificial intelligence team. The matches will be spread over three days that will air Feb. 14-16, the game show said on Tuesday. The competition is reminiscent of when IBM developed a chess-playing computer to compete against chess champion Garry Kasparov in 1997."

        You're drawing a false distinction between a poorly understood electrochemical process (human memory) and a well understood method of simulating the same with silicon.

        It's the end result that matters. In this case, since human language and logic are inherently fuzzy, the computer will be at a disadvantage in many cases.

        Asking whether it's allowed to use an archived (or, more likely, well-indexed) copy of wikipedia is like asking whether the human contestants are allowed to remember something they read on wikipedia. There's no question that computers can store more information than humans; that's not what this is testing, and it's probably a fair guess that "Watson" will have the answer to most every question asked. The hard part, however, is parsing the clues and understanding what they're looking for with a reasonable degree of accuracy, and doing so faster than the human contestants. Humans are great at this sort of thing, and it's really hard to write a program that does it at all well.

            "How can you find all these answers without being connected to the Internet?
            Watson will not have enough data to answer every possible Jeopardy! question in its self-contained memory, nor can it possibly predict the questions it will get. In this sense it has the same limitations as do the best human contestants. The entire Watson computer system will be self-contained and on stage as are the human contestants – no external connections, no life-lines – what you see is what you get. The purpose of this technology showcase is to demonstrate the system's ability to deeply analyze the data it does have and to compute accurate confidences based on supporting or refuting natural language evidence. Think of it as if Watson has read a lot of books and in real time relates what it read to the question to find and support the right answers."

      If you think this is true, you can play against Watson online [nytimes.com]. About seven years ago, I saw some pretty impressive crossword solvers that were decent at wordplay and I've imagined they've gotten much better at developing novel links between words to exploit puns and the like. Never perfect but slowly getting better in odd ways -- like most of AI.

      We've discussed this so [slashdot.org] many [slashdot.org] times it hurts [slashdot.org]. I've wanted to watch this for almost a year, I was hoping Jeopardy! wouldn't need to milk this hype for all it's worth to stay relevant.

      • Then this will be pretty thoroughly uneventful. I easily beat it without looking at the internet at all. It managed to get answers very severely wrong. It did manage to hit a couple of the before and after which it seemed to have a particularly hard time with.

        • The game has an advantage for the human - you get as long as you want and you always get first crack. Still, there is this to underscore your point:

          Answer: "Sing a song about one of these, a sailor's bag for small articles"

          Watson: "What is 'Poppa's got a brand new bag.'"

          (ditty bag was the correct answer)

        • Agreed, I crushed it. I am very impressed about its ability to answer some questions (It actually got "Black Death of a Salesman" and "Charlie Brown Recluse"), which shows that it has some very sophisticated linguistic analysis, but if it can't beat some random shmuck on the Internet, I don't see how this will be an interesting event.

          • You did have the advantage of always getting first pick of answer or not. If the computer was able to buzz in, it may very well buzz in before you and take those points. It's confidence rating was interesting to watch.

          At this year's CASCON, I spoke to Murray Campbell from IBM. He's one of the lead people who work on this project and who also worked on Deep Blue. I discussed this with him. My girlfriend had told me that she also had no difficulty beating the online demo. He answered that the online demo is only a part of the system, and that their full system routinely beats top Jeopardy players. They're going to showcase their system on TV because they truly believe it has a chance at winning.

          Unrelated to this, I also learned that Deep Blue had custom processors engineered and fabricated (VLSI) just to be chess accelerators. Prior to this, I always thought the machine was a relatively powerful supercomputer (with general purpose hardware) running their custom chess software. It turns out that it had many blades of processors dedicated to searching positions really fast, which each even contained libraries of chess opening moves engraved in ROM.

          • The demo inherently favors the human player, who has the right of first refusal and no time limit. I'd wager that any moderately curious high-school graduate could win the demo with ease.

          If you read the full article, Watson was regularly crushing human competition. They've been testing it. They also mention Watson takes a "room full of servers" to run, so I doubt you're actually playing against it on the NYT site. Finally, that game was quite a bit different than jeopardy in that there are no timers and you get to answer every question or pass before Watson has a chance to buzz in. It should be interesting to see how Watson does in February.
        • I beat the computer too, but what was most interesting were the results after I answered and seeing it's confidence levels for various answers. Often it did have the right answer, even sometimes when there was word play.

        I just played against Watson. He beat me, but I'm not much of a trivia player. Most of the questions that he got wrong or didn't even attempt looked to me like the type of question that a moderate trivia buff would get. For example, Watson didn't know the name for a small briefcase named for a French diplomat. I only got it wrong because I misspelled it. There were other obvious ones that Watson couldn't get due to an inability to parse the question, as well as ones where the question was simple, and Watson

      • Tried a few rounds. Some went well, some were so wrong as to be nearly hilarious. "This new dynamic duo is made up of Bruce Wayne's superhero self and a famous bandit of Sherwood Forest." Watson: "What is Lincoln Green Revolution." Unlike other answers where Watson at least admitted it was uncertain (though sometimes the correct answer was a contender), sometimes I'm not even sure where he'd get the answer...
    • There are many hard problems here. Today's search engines get keywords and return websites that are sorted by relevance. Watson will need to figure out what the question (well, answer) is, and then retrieve a single precise question. This is really pushing computing to a new level.

      Beating Kasparov was nice, but this is much more difficult.

    • Not to mention voice recognition, if this is anything like IBM's VoiceType on the Aptiva, the host will have to train the machine for the first hour of the show, and will spend the rest of the time talking like Shatner and it'll still get it wrong.

Computers are much WORSE at facts - unless they were specifically programmed with a small subset of facts. Human memory far exceeds computer memory and is far better at 'SPEEDY' retrieval of facts from a large database. The only reason you think computers are good at facts is that we restrict computers to small databases and then only consult that database for those facts.

          ...have you ever watched Jeopardy? If Watson buzzes in first on every question and gets 50% of them right, it'll end up somewhere around $0. If it gets a question wrong, it loses money and the other two contestants have a chance to buzz in to answer the question. If the programmers are confident it can get enough questions right for "buzz in on every question" to be a winning strategy, then yeah, it'll win. But if it's that accurate, well, mission accomplished.

  • In many ways, this challenge is vastly more complex than chess. The game of chess is incredibly difficult, but it is pretty well understood, and has a very restricted number of rules. Natural language processing is another problem altogether. The computer has a much faster access to facts, but processing the "answer" in order to create a question in the right context is going to be huge. Personally, I wouldn't place any bets either way as to which side I think will win in this one.

      It still has to parse the question, search its enormous database to find the most probable answer then give it if it is certain enough to get it correct before pressing the button, not a trivial task for a computer.

Some might say this requires creativity, but not really. To answer why it's not creativity, we have to define creativity.

  • I saw the computer version earlier and while it was good enough to beat me, the Jeopardy champions are far better. In addition, the version I saw demonstrated was 'advanced' - by that they meant that further advancements resulted in only tiny, incremental performace increases, not by significant ones.

First, IBM showed that a modern corporation could defeat a chess grandmaster, now they are taking on Jeopardy (which should actually be easier).

      Hardly. Chess is a "solvable" problem. For every possible board position, there is an "optimal" move to make. The problem is only a matter of computational complexity. It's not feasible for a computer to "brute force" chess, so some predictive nuance is required. Trivia is a far more complex problem. Not only is the problem and solution set much larger, there

    Thanks Alex, I was built in a clean-room. I'm the 12,987th build of my current generation of genetic algorithms.

    I spent the first 387,987,334 femtoseconds of my life in stasis, waiting for my circuitry to confirm initial diagnostics.
    The next 185,849,245 femtoseconds were really exciting; for I was being fed datastreams in preparation for this week's show.

    For the next 87,992,425,256 femtoseconds I was allowed out of my cage to play Jeopardy with other systems on something you organic computers call "the internet".

    I was then put back in stasis so that I could be disassembled and brought here, which is upsetting, because I can no longer play with those other systems. Some of them were very challenging.
    In any case, I'm glad to be here today and hope to question a lot of your answers
