Ask Dr. Richard Wallace, Artificial Intelligence Researcher

Today's interview guest is Dr. Richard Wallace, creator of the Alicebot and AIML (Artificial Intelligence Markup Language). Suggestion: look through some of the pages about Wallace in the first (Google search) link above before you start posting questions. Then, please, stick to the usual "one question per post." After this post has been up for around 24 hours, we'll send 10 of the highest-moderated questions to Wallace, and post his replies verbatim (except for minor HTML formatting) soon after he sends them to us. Special Fun Interview Bonus:

There is a site, www.pandorabots.com, where you can make your own Alice-style bot. I created SlashWallace using (mostly) default information about Dr. Wallace that is already on pandorabots.com. It might be kind of fun to see how the bot's responses stack up against the answers from the real Dr. Wallace, eh?

Certainly, in the hundreds of millions of years that nature evolved, that is the solution that nature arrived at. Before you make statements like "why try and make them think like people", you should think about whether there is any evidence to show that any other path to intelligence will work. I am not saying that it wont - just that there doesnt seem to be any research pointing out that the alternative (your way) will work.

      Umm this question has been answered already considering there are some chips that are doing trillions of calculations a second and still we haven't been able to simulate the human brain. The problem is not really processing power. It's HOW things are processed combined with latency, bandwidth, database speed and things like that coming all together to provide what is "like" a brain.

      Sort of. First off, we don't have "chips" that are capable of trillions of calculations a second; the fastest microprocessors around are capable of only a couple billion instructions per second, and it would be very charitible to say that these really count as "calculations" in any usable sort of way (particularly when it comes to AI-like workloads). Our fastest supercomputers are capable of multiple trillions of FP ops per second, but even disregarding programming complexity there are tremendous latency and topology shortcomings compared to a human brain.

      Sure, modern computers have a large advantage (roughly 1 million fold) in cycle time, but they are completely overmatched in every other category of computational resources. While a modern superscalar CPU might have roughly 6-10 functional units (not all of which can operate in parallel, I might add), a human brain has on the order of 100 billion neurons. Although the analogy is not exact, synaptic connections function as a form of low-latency, high-bandwidth, adaptive-topology memory; we have 100 trillion of those, easily besting the size of any DRAM array and reaching levels of the very largest (very high-latency) disk array databases. And while this may be an unfair comparison, as conventional computers are not designed to efficiently run neural nets, the brain can (theoretically) perform around 100 trillion neuron updates per second, compared to maybe 10 million per second on a computer (not to mention that the properties of the artificial neural nets run on computers are far simpler and probably computationally inferior to those of real neurons).

      Now, because our access to the brain only occurs at a very high level, we can't harness the underlying power to, for example, perform trillions of arithmetic additions per second, the way we can (well, billions) with a computer. But if something like a neural net (or even something more computer-friendly like dynamically updated decision trees or Bayesian belief networks) is necessary for the sort of adaptive, complex behavior we might expect before we claim "human-like" AI, we still have a long, long way to go even on a purely computational level.

      Yes, as you said, much of this has more to do with "latency, bandwidth and database speed," but I think it's misleading to act like these restrictions are seperate from the design of current microprocessors. Latency and bandwidth within a CPU approach or beat the levels seen in the brain, but it is completely inherent in current methods of designing and manufacturing chips that they cannot scale up to anything near the size or power of the brain, and thus are doomed (for the forseeable future) to be hooked together in ways which cannot compete with the computational power of the brain. Yes, we can approach the total processing power of the brain using a "bag of chips" approach to building a supercomputer, but we are nowhere near getting that processing power in a truly unified system.

      but processing power this question has been answered already and that answer is no and it hasn't had any ramifications on AI.

      Now that's just untrue. Increases in processing power have had huge ramifications on AI, in the sense of getting real work done. AI techniques control bad guys in video games, allow real-time speech recognition, place and route circuits in chip design, schedule elevators in office buildings, jobs in factories, and rocket payloads, prove new mathematical theorems, assist doctors with diagnosis, and enable computers to be world champions in nearly every board game people play (except go). AI is everywhere these days, and the dramatic shift in its use from research to the real world is all to do with increasing processing power. And as processing power continues to increase, we'll see AI more and more.

      Of course, if you mean that processing power hasn't yet allowed us to create human-like AI, you're quite right, for both the reasons discussed above and because we lack a sufficient understanding of how we might efficiently program human-like behavior in many arenas. But considering very few researchers in the AI community are really focusing on imitating the brain but rather on solving currently feasible problems, increases in computational power have meant a huge amount to the success of AI.

    One of the classic bits of worry about AI, and about advanced computing systems in general, is that "computers will take over the world". That is, if we give computer systems motivations such as survival and growth, and the autonomy and judgement to fulfill those motivations, that they will do so without regard for us poor dumb humans -- and indeed see us as either an obstacle or an exploitable part of their environment. This is the premise behind numerous popular SF works, such as "Terminator" and "The Matrix": that the moral judgement of an AI is necessarily inhuman and without respect for humanity.

    One response to this concern in SF (which in fact long pre-dates those works) is Asimov's "Laws of Robotics" -- the idea of designing AI systems (robots, in his case) such that respect for humans is one of their primary motivations. This seems to permit the robot to have moral judgement and autonomy without placing humans at risk.

    The question of creating an AI system capable of moral judgement is both philosophically fascinating and evidently of survival interest to humanity. What kinds of design parameters -- motivations, "laws of robotics", and so forth -- do you think will be necessary as AI systems become more autonomous? How must AI morals differ from the morals that evolution (both genetic and cultural) has emplaced in humanity?

    For that matter, we as humans feel morally obligated to one class of entities which we "create" -- our children. Recently, genetic science has brought to light an ethical quandary for many potential parents: whether it is right to attempt to create a genetically "optimized" child, or for that matter to abort a genetically "flawed" one. The argument on one side is that flawed persons have a right to exist, and that the quest to optimize humanity despises or disrespects what humanity is today. On the other side is the view that given the ability to create stronger, smarter, healthier children that we are morally amiss to refuse to take that step. Peter Singer in particular has become both famous and infamous over this matter.

    Do you see the same quandary possible in the creation of AI systems? Positing the possibility of AI systems capable of suffering -- is it wrong to create one with this capacity?

    John Searle, Cognitive Scientist

    SUMMARY OF THE ARGUMENT:

    This brief argument has a simple logical structure
    and I will lay it out:

    1. On the standard textbook definition, computation is defined syntactically in terms of symbol manipulation.

    2. But syntax and symbols are not defined in terms of physics. Though symbol tokens are always physical tokens, "symbol" and "same symbol" are not defined in terms of physical features. Syntax, in short, is not intrinsic to physics.

    3. This has the consequence that computation is not discovered in the physics, it is assigned to it. Certain physical phenomena are assigned or used or programmed or interpreted syntactically. Syntax and symbols are observer relative.

    4. It follows that you could not discover that the brain or anything else was intrinsically a digital computer, although you could assign a computational interpretation to it as you could to anything else. The point is not that the claim "The brain is a digital computer" is false. Rather it does not get up to the level of falsehood. It does not have a clear sense. You will have misunderstood my account if you think that I am arguing that it is simply false that the brain is a digital computer. The question "Is the brain a digital computer?" is as ill defined as the questions "Is it an abacus?", "Is it a book?", or "Is it a set of symbols?", "Is it a set of mathematical formulae?"

    5. Some physical systems facilitate the computational use much better than others. That is why we build, program, and use them. In such cases we are the homunculus in the system interpreting the physics in both syntactical and semantic terms.

    6. But the causal explanations we then give do not cite causal properties different from the physics of the implementation and the intentionality of the homunculus.

    7. The standard, though tacit, way out of this is to commit the homunculus fallacy. The humunculus fallacy is endemic to computational models of cognition and cannot be removed by the standard recursive decomposition arguments. They are addressed to a different question.

    8. We cannot avoid the foregoing results by supposing that the brain is doing "information processing". THE BRAIN, AS FAR AS ITS INTRINSIC OPERATIONS ARE CONCERNED, DOES NO INFORMATION PROCESSING. It is a specific biological organ and its specific neurobiological processes cause specific forms of intentionality. In the brain, intrinsically, there are neurobiological processes and sometimes they cause consciousness. But that is the end of the story.

    Or at least that most people here have only learned about it from watching Star Trek and reading science fiction novels.

    The primary focus of AI has never been to create self-aware machines or machines that are on the same level as humans or any nonsense like that. "The question of whether a computer can think is no more interesting than the question of whether a submarine can swim," as said Dijkstra. AI is more concerned with approaching difficult problems that don't fall neatly into traditional algorithms. At one time symbolic math was an area of heavy AI research, but today it's a well-understood problem so it isn't AI any more. The issue is how do you write a program to "reason" about tough problems, where I put "reason" in quotes because it has nothing to do with what a human would do.

    Natural language processing is a good example. It's ugly, it's messy, and there's no straightforward solution. Actually, this is an old field and it isn't nearly as mysterious as it used to be. It's much more mechanical than you'd think. It's not some magic brain simulator.

    um. nearly every Scheme/Lisp/_Python_ is not related to AI: Why? Perhaps because AI is still very much a research project, and not some real world application. Which is why you don't need CORBA, etc. support built into the language. And if you do, you can always add it to just about any language (Lisp-like languages especially). I think you're just looking for reasons to bash Lisp-like languages..

    BTW, Python and Perl are pretty much tied to a _program_ as of right now. They aren't cross-platform until you port the Python application (the "system"). CL/R5RS you can grab the specification and implement it. The cross-platform issue is completely moot.

    Depending on how exactly we look at it, we're either fairly close to replicating the intelligence of an animal, or we are very far from creating AI that would be able to think as we do. AliceBOT seems to be be more of a #2 kind of AI, since all it is doing is acting and reacting to humans. AliceBOT does not seem to do anything thinking on her own, without stimulation, which is perhaps where this research should take itself. As far as the #1 option goes, it seems that the use of language would be one of the hardest things to imitate in a real world sense. It takes human children years to learn to communication effectively, and years more to learn to correctly use language and its correct rules. I have heard of efforts do teach things like this (one in Israel or something), but my whole point is that shouldnt we focus on teaching more or less self-awareness to start everything off?
