Reading Guide To AI Design & Neural Networks? 266

Raistlin84 writes "I'm a PhD student in theoretical physics who's recently gotten quite interested in AI design. During my high school days, I spent most of my spare time coding various stuff, so I have a good working knowledge of some application programming languages (C/C++, Pascal/Delphi, Assembler) and how a computer works internally. Recently, I was given the book On Intelligence, where Jeff Hawkins describes numerous interesting ideas on how one would actually design a brain. As I have no formal background in computer science, I would like to broaden my knowledge in the direction of neural networks, pattern recognition, etc., but don't really know where to start reading. Due to my background, I figure that the 'abstract' theory would be mostly suited for me, so I would like to ask for a few book suggestions or other directions."

        The great thing about the PDP books is that they make almost NO assumption as to what the reader's background is. There's no code, a bunch of pictures, and something in there for everyone. Each chapter is written with a specific goal in mind, and by leaders in the field--there are chapters on the mathematics of the networks, the dynamical properties of them (i.e. how they can be thought of as boltzmann's machines), as well as lots of ideas for applications and specific studies of how real experiments worked

      Also seconded. Russel & Norvig. Artificial Intelligence: A Modern Approach [berkeley.edu] is a good book, well illustrated, and generally lacks the undecipherable academia-speak that pervades lots of AI literature.

      Here's an article that was particularly influential on me and some of my friends: Brooks, R. 1991. Intelligence Without Reason. MIT AI Memo num 1292 [mit.edu]. Even though it is 'just' a tech report, it is frequently cited. He had another one, Intelligence without Representation, which is also good.

      Somebody else mentioned the McClelland and Rumelhart PDP (neural networks) book, and it is also still quite good in spite of its age.

      The interesting thing about AI (to me) is the funny mix of domain expertise. You have philosophers, sociologists, cognitive scientists, psychologists, computer scientists, and mathematicians. That's not a complete list---I'm in human-computer interaction and design research.

      But because of the motley crew of domains you have a hundred people speaking a hundred different dialects. Some people put everything in really mathy terms, and their journal articles look (to me) like they are written in Klingon. Then you have others who write in beautiful prose but don't give any specifics on how to implement things. Still others express everything in code or predicate logic.

      The oldest school of AI holds that you can reduce intelligence to a series of rules that can operate on any input and make some deterministic and intelligent sense of it. That works to a degree, but it falls apart at some point partly because of the computational complexity (e.g. the algorithm works if you have a million years to wait for the answer). Another reason it falls apart is because there are some kinds of intelligence that can't be reduced to rational computation (e.g. I love my wife because of that thing she does...).

      There's a newer kind of AI that is based on having relatively simple computational structures that eat lots of data, "learn" rules based on that data, and are capable of giving fairly convincing illusions of smartness when given additional data from the wild. Neural nets fall into this category.

      A third kind of AI brings these two schools together in the belief that there are fundamental computational structures like Bayesian Networks that can model intelligence* but those structures by themselves are insufficient and must be able to adapt based on exposure to real data. So instead of having a static BN whose topology is defined at the start and remains the same throughout the life of the robot, we can have a dynamic BN whose structure changes based on the environment.

      I remember reading a recent article by John McCarthy arguing that all this statistical business is hogwash, and that the old school positivist, reductionist approach will eventually win. He's a smart guy, inventor of LISP and a Turing Award recipient. It seems his view is in the minority, but I'm not one to say he's wrong. However, my inclination is that the third hybrid group is probably going to be the one to make the most progress in the years to come.

      The reason for my preference to the hybrid school could probably be best explained by Lucy Suchman's Plans and Situated Actions [wikipedia.org]. I can't really do her thesis justice in a few sentences, but the short version of her argument is that there are plans (the sequence of steps that we think we are about to carry out before performing some task) and actions, which is the set of things we actually do. In my mind, a plan corresponds roughly with the underlying computational mechanism, but the actions correspond with how that mechanism executes and what happens when the underlying structure is insufficient, wrong, misleading, or fails.

      Hope that helps.

    There is a very big difference between AI - which is based on guesses about how "intelligence" works, and studies of brain function. I'm going to make a totally unjustified sweeping generalisation and suggest that one reason that AI has generally been a failure is because we have had quite wrong ideas about how the brain actually works.

    So my feeling is that the first people really to get anywhere with AI will either work for Google or be the neurobiologists who finally crack what is actually going on in there. If I wasn't close to retirement, and wanted to build a career in AI, I'd be looking at how mapreduce works, and the work being done building on that, rather than robotics. I'd also be looking as seriously parallel processing.

    So my initial suggestion is nothing to do with conventional AI at all - look at Programming Erlang, and anything you can find about how Google does its stuff.

Aside from the intuition that the brain is a massively interconnected network, no one is really sure what aspect of neural network functionality is necessary for intelligence. My advice to you is to spend time coming to terms with the abstract nature of intelligence rather than coding up elaborate projects. This link [uh.edu] is a philosophical discussion on directed behaviour which I found quite interesting (if a bit vague, which is the mark of philosophy). Also, as you become familiar with the literature, you will see many examples of algorithms which claim to model certain aspects of intelligence. These algorithms work because they have a reliable and unambiguous artificial environment from which they draw their sensory information. The problem with practical artificial intelligence is that the real world is extremely ambiguous and noisy (in the signal sense). Therefore the problem is not creating an algorithm which can emulate intelligent behaviour but solving the problem of taking the empirical information of the sensory input and producing from that data a reliable abstract representation which is easily processed by the AI algorithms (whatever they may be, neural networks, genetic programming, decision trees etc) Good luck.

    I would strongly recommend starting with a text book on Cognitive Psychology, or reading it in parallel. AI tends to overlook the fact that intelligence is a human trait, not the most efficient algorithm for solving a logic puzzle.

    I read "On Intelligence", too. While Hawkins has some interesting thoughts, I was less than inspired. Probably because I read John Searle's "Rediscovery of the Mind" first. Actually, most of Searle's work, as well as the work of Roger Penrose has led me to the conclusion that the Strong AI tract is missing the boat. The Strong AI proponents, like Hawkins, believe that if we build a sufficiently complex artificial neural network we will necessarily get intelligence. Searle and Penrose have very convincing arguments to suggest that this is not the right path to artificial intelligence.

    Realistically, how could one build an artificial brain without first understanding how the real one works? And I don't mean how neural networks function; I mean how the configuration of neural networks in the brain (and whatever other relevant structures and processes that might be necessary) accomplish the feat of intelligence. We still do not have a scientific theory for what causes intelligence. Without that, anything we build will just be a bigger artificial neural network.

    Also, the thing that Strong AI'ers always seem to forget... An artificial neural net only exhibits intelligence by virtue of some human brain that interprets the inputs and outputs of the system to decide whether the results match expectation (i.e. it takes "real" intelligence to determine when artificial intelligence has occured). Contrast this with the way your brain works and how you recognize intelligence from within, then you'll realize just how far from producing artificial brains we really are...

    I'm not saying that artificial intelligence is impossible, and neither is Searle (Penrose is still on the fence). I'm just saying, don't think you can slap a bunch of artificial neurons together and expect intelligence to happen.

    • Did you in fact read "On Intelligence". I did. You're not describing anything I found in Hawkins's ideas. And I can certainly tell you he's not the type to say that intelligence magically happens once you get enough complexity. You are especially unfair to say,

  • I've never understood the draw behind "neural networks" ... it's a really cool-sounding term for an otherwise not-so-exciting algorithm.

    A neural network lets you determine an approximation to a function for which there may be no closed-form expression. It's basically a piece-wise linear approximation with heuristic edge-waiting, where the edge weights are "trained" by inputting numerous samples to the "neural network".

       

    • It sounds as if you're describing a feed-forward network. Things get much more interesting once you bring feedback paths into the picture. Try googling "Adaptive Resonance Theory (ART)" for one particular architecture, or consider your own grey noodle as the ultimate proof of concept of the power of neural nets!

  • Well, this is an easy one. You should read books on how the brain is built. I would read "On Intelligence" by Jeff Hawkins to start. The idea is that you want to see how the brain functions so that we can emulate it. That means you need to understand the functions of both brain hemispheres. The left generally handles linear sequential pattern stream processing while the right handles visual simultaneous pattern stream processing. In short, the left handles language, the right images. The brain functions the

But that is like saying computers are built with many interconnected transistors and I want to design a web site so I'll study the physics of semiconductors. No, if your goal is web site yu ned to work at a higher level of abstraction, maybe at the level of PHP or Java Script.

    • To answer my own post, What I'm saying is that the brain likely does NOT store information the way modern computers do. In a computer you can point to the physical place that any bit is stored. It will live inside a cell of RAM or a spot on a disk.
