An anonymous reader writes "Passing the Turing test is the holy grail of artificial intelligence (AI) and now researchers claim it may be possible using the world's fastest supercomputer (IBM's Blue Gene). This version of the Turing test pits a human conversing with a synthetic character powered by Rascals software crafted at Rensselaer Polytechnic Institute. RPI is aiming to pass AI's final exam this fall, by pairing the most powerful university-based supercomputing system in the world with its new multimedia group which is designing a holodeck, a la Star Trek."

    I think the people behind this misunderstand the difficulty (and purpose) of passing the Turing test. The problem isn't in manufacturing a believable back story for your program's "character". The problem is in communicating effectively in spite of the inherent ambiguity, fuzziness, and confusion of human languages. I think it's very unlikely that any team is about to meet this threshold.

      the real turing test is being able to Phish in a chat room. One you can automate that you're golden. and it's pretty unarguable it passed a turing test. Slashdot had a article a while back about robo-chats doing just that but they relied on pretending to be non-native english speakers.

      I wonder if it's easier to do this in Japanese than English. From what I've read Japanese is easier to text message in because the object and direct object are usually inferred and there are no cases or articles. A single sentence can be one character and just a verb. Thus by constraining the nuance into discrete choices rather than sparsely populated product space of self-consistent cases, predicates and adjectives, perhaps japanese would be easier to generate turing worthy text.

      Or maybe the reverse is true. But I'd bet one was a lot easier than the other.

      • Japanese is a pro-drop language, in that you can leave out subjects or objects in speech if it's clear from discourse what you're talking about.

        But Japanese definitely has a case system where the inflectional morphology is indicated by particles that follow the modified noun.

        Japanese has all kinds of complexities. They have complex conjugations first of all, then there's the whole system of politeness depending on who's being addressed although that may be less relevant online. While at it's core Chinese is fairly intuitive and straightforward it quickly gets very complex.

        Both Japanese and Chinese use all sorts of expressions, many of which make no sense whatsoever when translated literally. This becomes apparent when trying to use those translation tools. The translation ends up being complete gibberish to the point of being comedic.

        Because people of so many nationalities speak English it's easier for an AI to fool people because there really is no standard for the language. English-speakers are used to hearing it spoken in all sorts of different ways, with a wide variety of expressions.

        Automated chats are always obvious for what they are because they tend to stupidly repeat the same few comments over and over again. They're also incapable of responding properly to a user's comments, and colloquialisms always trip up these systems.

    Somewhere around five years of age, however, children begin to have second-order beliefs--that is, beliefs about the beliefs of others, enabling them to understand that other people can have beliefs different from their own. Now, Bringsjord's research group claims to have achieved second- and third-order beliefs in their synthetic characters.

    Funny how recursion is always a key for "real" abstract thoughts. You could think that adding them to the langage of the AI will bring all the problems it does in logic, but then you realize that real humans always doubt sentences with three levels of recursions (or above), and try to avoid them.

    That makes this approach all the more interesting.

  • It is interesting that they have used a 'guinea pig' student to 'bare all' to the knowledge base. It would seem, then that this AI is in fact a type of facsimile of this student.

    As we become more comfortable with accepting communication with each other through more abstracted proxies - like common chat applications currently and the recent neural voice collar (which pumps out a synthetic voice - even further proxy) - I wonder if we will in fact see what the author Stephen Baxter speculated, artificial clones of ourselves or our personalities handling our daily affairs.

    I don't think it's too far out there to imagine interacting and planning a meeting with someone over the phone, only to find out later you had been talking to an AI facsimile of that individual.

    What would (and may) be stranger yet, is considering the possibility that two AI facsimiles may in fact carry out real work or meetings from start to finish completely without the interaction of their 'owners'.

      Well, imagination is a great thing but I've not yet seen anything that even comes close to that kind of imitation of a human. Not even close. It takes max of two questions to figure it out that it is a machine. The scope of what the facsimile is programmed with/for can be outstripped quickly.

      It will be quite some time before we have conversational intelligence out of AI systems. Retrieval speeds on Google searches are good, but at conversational pace, sifting through the information for some trace of relevance to the conversation is still going to be stilted and slow. Even then, finding some relevant response to a topic is not something that people do well.

      We each have a sphere of stuff that we are familiar with. It is a human trait to act in one of several ways when conversation goes beyond that:

      - walk away/ignore
      - talk out of our asses like we do know when clearly we don't
      - quietly observe to learn what others know
      - change the subject

      That as an example of what current AI conversation applications are not capable of.

      In the case of an AI answering machine making a meeting appointment, it would only take one odd question, like: how about those cowboys? to throw the process out of whack if you did not know that you were talking to a machine.

      AI does not thread thought and memories in the same way that we do, and this is part of what humans call humor.. when the story being told mismatches the thread/plot that we have in our heads. That depends hugely on the experience of the human involved, and the depth of their retained knowledge. both of these are missing in AI systems, and current technology will not allow for faking it past some limited point. The ability to switch to another 'almost' related conversation is something that AI cannot do without great memory stores, fast search/retrieval etc.

      Imagine it like this: every sentence in a conversation is essentially a chess move. The game of chess has a finite bounded domain. A conversation with a human does not. The problem is far greater than a mimicry.

        Actually, current AI "conversation" applications do all of the above all the time... that's one of the things that make them so easy to detect.

        To be fair, that question, without any context, would confuse the majority of human beings also. Not everybody knows the names of American football teams ;^)


        The game of chess has a finite bounded domain. A conversation with a human does not.


        Are you sure? Human conversational domain might be finite, albeit quite a bit larger than the chess domain. At some point it becomes very difficult to tell the difference between "infinite" and just "very very very large"...

    "That's how we plan to pass this limited version of the Turing test."

    If it's a limited version of the Turing Test, then it's not the Turing Test. They don't actually define exactly what the limits are. But any open ended test is doomed to failure based on our state of the art in A.I. (read: there is no science of Artificial Intelligence, in the sense of artificial cognition).

    "What do you think a typical mother would say if she found out her daughter was going to enter the porn industry."

    "Why do you think children have emotional attachments to their parents?"

    "Which is worse, racism or sexism?"

    "Would you rather be a fireman or an astronaut, and why?"

    Any sort of open-ended question that requires human cultural knowledge and asking it to support its conclusion is going to cause it to barf.

    Now, if the point of this is whether you can fool someone into thinking the Avatar was human when they didn't know it was a test, well, who cares? Eliza was able to do that back in the 1970s.

    Lastly, who says the Turing Test (or any A.I. test) needs to take place in real time? I would be impressed if they came back with a human-level answer in a month of processing time. That's equivalent to a computer 2.5 million times faster than a computer that could produce the answer in one second. That they can't even do that should tell people that speed is not the problem in A.I. research. We have absolutely no fundamental model of how it all works.

    For those of you who don't know what the Turing Test is (how did you manage to find Slashdot?), to quote from Wikipedia

    ... a human judge engages in a natural language conversation with one human and one machine, each of which try to appear human; if the judge cannot reliably tell which is which, then the machine is said to pass the test. In order to keep the test setting simple and universal (to explicitly test the linguistic capability of the machine instead of its ability to render words into audio), the conversation is usually limited to a text-only channel ...


    From the summary this "test" is not a strict Turing Test as it appears to be the machine talking to a human, alone, with no second human also talking to the first human. I could be wrong of course.

    One of the things that makes this test so special, is that if you cannot tell the difference between a human and a computer, then essentially the computer is intelligent. Why? Because if you cannot tell the difference, what does it matter if the machine is really intelligent or not? Is the machine was really thinking or was it just cleverly programmed? The point is however, if you can't tell the difference, what does it matter? (Incidentally, I apply the same argument to the "question" of "free will".)

    Anyway, if this machine (or personality) consistently passes a proper Turing Test, then yeah, that's pretty cool, and I want one on my computer, well so long as the personality type is compatible with my own (not a Marvin please...). (And I have a partner, so no need to make such jokes...)
    • And as I understand it, the test they propose is not only one-sided, it is limited in scope. That is not a Turing Test, in which one is supposed to engage in free conversation. There is a world of difference.

    One of the problems for any entity trying to communicate like a human is that we share some common knowledge which is based on our physical existence (pigs can't fly, but fall etc.) Some AI projects like (Open)Cyc [wikipedia.org] have tried to feed their AI with a very large number of simple facts, but to "understand" some concepts you have to experience them. Try to explain the difference between red and blue to someone who was born blind.

    The 3D communication (holodeck) aspect mentioned is therefore an attempt to have an AI "living" in a human like space, to enable it to develop a similar world view. What's new about Rascals (Rensselaer Advanced Synthetic Architecture for Living Systems) seems to be something else ("Rascals is based on a core theorem proving engine that deduces results (proves theorems) about the world after pattern-matching its current situation against its knowledge base.") that is very computing intensive. Whether this will make any real difference remains to be seen, a lot of other approaches have failed and they so far have only succeeded with very limited models.
