There was one little line in this post that struck me, and I wanted to
comment:
Quoting Ed Porter <[EMAIL PROTECTED]>:
With regard to performance, such systems are not even close to human brain
level but they should allow some interesting proofs of concepts
Mentioning some huge system. My thought was, wow, that's just sounds
sad. But I guess it depends on what you mean by performance. One
thing that computers now way exceed brain performance in is
reliability of the operations. Sure, it's difficult to say what a
basic brain operation is (is a synapse reaction equivalent to a
multiply accumulate?), but one thing that can be said about them is
that they aren't very reliable or precise. They have a sort of a
range of operation, where they kind of will act in a certain way given
an input. It's got to be really hard to get valuable behavior out of
this kind of a system, so the brain uses massive redundancy. Now, it
might well be that in addition to just the reliability, this kind of a
system gets other value from it, like a nice probabilistic operation
that has additional value in itself. Maybe the inherent
unpredictability is part of what we mean by intelligence. Personally
I suspect that to be true. But this all stands in great contrast to
how computers naturally work--obeying information processing
instructions with absolute precision (possibly error-free, depending
on how you look it).
There is a sort of mismatch between good human brain behavior and good
computer behavior. It seems like the AGI project is about making a
computer act like a good brain. We can focus on how to get a computer
to act in ways that are ideal for a brain to act intelligently. And
by this I mean something like having some basic operations and systems
that can be used in all situations. But I think it might also be good
to try to think of it in terms of looking for the best ways for a
computer to be intelligent. I'm a patchwork AGI kind of guy, and
while surely there must be some general mechanism, it seems to make
sense that there could also be many very finely crafted modules.
Unfortunately, if we are restricting modules to human written modules,
then that's the basic problem. A basic function of an AGI should be
that it can write programs for itself to handle tasks. Or I guess for
other systems. But if it can do that, then these programs don't need
such huge amounts of computer power.
