Subject: re: Searle questions
From: dank@moc.Jpl.Nasa.Gov (Dan Kegel)
Date: Mon, 12 Mar 90 19:42:42 -0800
I suspect that Searle's Chinese Room claim is just a consequence of
a more basic premise, which can be rephrased:
"Mind you, I'm not saying that computers can't think. It's
computers that are based on pure symbol manipulation that I claim
cannot think. Specifically, they cannot think because they do
not duplicate the causal powers of brains."
Even a computer running an exact simulation of a brain does not satisfy him.
As has been pointed out, it is possible in principle to graft biological
sensory organs [aka causal powers] onto such a computer. Searle would,
if pressed, probably admit that the resulting system could think and
understand. After all, it has duplicated a brain's causal powers, hasn't
it? {Can somebody supply Searle's address, so we can direct the question
to him?}
But are sensory inputs really needed for thought? Imagine disconnecting
a brain's "causal powers" one by one. Does thinking cease when the nose
is disconnected? No. When the eyes are shut? No. When the angiotensin
receptors that mediate thirst are removed? No again; in fact, it seems
reasonable that thought could continue when all sensory input is removed.
The remaining causal power is memory, which I state is sufficient.

>(including mixing various composers).
Readers more interested in what can be done with neural networks may wish
to check out Peter Todd's contribution to the 1988 Connectionist Models
Summer School. Todd is a psychologist, and he seems more concerned with
modeling phenomena which have been observed in psychological experiments.
I would say there is still some doubt as to how relevant those
experiments are to music as it is actually practiced, but at least Todd
appears to be approaching the problem more scientifically.

The two most recent issues (vols 12 and 13) of "Computer Music
Journal" are completely devoted to neural nets and connectionism as
applied to musical composition and models of music perception. Todd has a
GREAT article in vol 13 on a recurrent network he developed for
algorithmic composition. There are also backpropagation models of pitch
perception (Jenkins), bidirectional linear nets for inferring tonality
(Bharucha), and in vol 12 an ART system for musical classification.
This semester I am working on applying invariant object
recognition to attempt to model the recognition of musical melody
independent of key signature (invariance with respect to tempo and mild
distortion invariance are also desirable). I have not seen this attempted
anywhere in the literature that I've seen so far. If anyone has seen such
an attempt, PLEASE respond in a followup posting and/or by e-mail. Thanx
much.

Thanks for coming to my rescue, Bob! I received two electronic mail
requests for details but was tardy in responding due to being snowed
under by two papers I'm trying to wrap up! Nevertheless, your citation
had better get corrected before things get out of hand. The two issues
are Numbers 3 and 4 of Volume 13 (not volumes 12 and 13). For those
interested in the specific articles, the Jenkins piece on pitch
perception and Gjerdingen's ART piece are in Number 3. Bharucha and Todd
are in Number 4. Personally, I did not think very much about the ART
article; but I am prepared to be persuaded otherwise.

>>>> In reply to Jason Kingdon's message about the problem with ART1:
Well, there are two ways to address you question: one answer is that,
indeed, you have found one of the problems with ART1. This problem has to
do with the fact that all top-down LTM traces are forced to 1 in fast
learning (or asymptotically in slow learning), so that the top-down
template match exceeds the critical strength regardless of the number of
nonzero weights in the top-down LTM trace. This can in fact be avoided in
ART2-3.
The other answer: The ART1 architecture was designed so that templates
can only shrink. This ensures that a maximal number of exemplars can be
categorized, depending on the vigilance level. If a single node has
non-zero strength, then at vigilance 1 you can only code the one-element
vector, but as you drop vigilance you can code more and more patterns
based on the "atomic" subpattern.
So basically you have shown that this categorization network, when
severely restricted in memory capacity, and when forced to make extremely
fine discriminations (vigilance=1) will only become stable on the most
*basic* pattern that can possibly grab a category (but can still code
supersets at lower vigilance).
Does this constitute an example of "rendering the system useless"?
I would consider it a fascinating feature.

ABSTRACT
We design a higher-order single layer, recursive neural network which
easily learns to simulate a deterministic finite state machine and infer
simple regular grammars from small training sets. An enhanced version of
this neural network state machine is then constructed and connected
through a common error term to an external analog stack memory. The
resulting hybrid machine can be interpreted as a type of neural net
pushdown automata. The neural net finite state machine part is given the
primitives, push and pop, and is able to read the top of the stack.
Using a gradient descent learning rule derived from a common error
function, the hybrid network learns to effectively use the stack actions
to manipulate the stack memory and to learn simple context-free grammars.
If the neural net pushdown automata are reduced through a heuristic
clustering of neuron states and actions, the neural network reduces to
correct pushdown automata which recognize the learned context-free
grammars.
