Having gone on at some length about the general issue of learning, I would only like to make a few minor comments about Mark's other article. First of all, I STILL think it is important that those of us who are really interested in BUILDING systems steer clear of words like "understanding." As I have pointed out in reviewing Turing's original paper, Turing was well aware of this danger and knew how to think like an engineer when the situation demanded. This bulletin board may be devoted to questions of philosophy, but that does not mean we should fall into all the traps inherent in philosophical digressions. The second point is that, even if we substitute some more mundane goal for "understanding"--such as some variation on Turing's "imitation game" which would provide a demonstration of learning-by-apprenticeship--we should not assume that we can attain any sort of "convergence" on that goal. We are not interested in systems that converge; rather, we should attend to systems that manage in the world. Systems that converge tend to lack the flexibility which such management demands. Having said all that, I want to raise one final point on this issue of "cheating." The fact is that what Mark calls "cheating" is part of what we accept as intelligent behavior among humans. After all, human memory is not so perfect that we never have to use a dictionary. (Indeed, we probably can all mention entries which we have consulted not just once but multiple times.) Indeed, what makes the GEDANKENEXPERIMENT interesting is that there is some point in the accumulation of experience after which such reference materials become USEFUL--rather than some obscure resource of symbols. Learning-by-apprenticeship is as much a matter of learning to use reference materials as it is learning to work with "primary objects." > >Of course, if you really want to try this on a task where there's no >opportunity for cheating, you'd get a hold of all the Mayan Hieroglyphic >sources and copy them all by tracing. I almost did that a few years ago... :) My conjecture is that you would certainly get as far as forming perceptual categories. You might even get a bit farther. However, you would never get to a point of associating what you were transcribing with any observations of the real world. That would severely inhibit your ability to "learn" very much. ========================================================================= USPS: Stephen Smoliar 5000 Centinela Avenue #129 Los Angeles, California 90066 Internet: smoliar@vaxa.isi.edu "It's only words . . . unless they're true."--David Mamet
