2 TRs

No, it's not another posting on quantum computers, but it's almost as
good: an announcement of two somewhat spacey TRs touching lightly on
the mind-brain problem.

The following 2 papers have been deposited in Jordan Pollack's 
immensely useful Neuroprose archive at Ohio State.  Retrieval

A REPRESENTATION OF REPRESENTATION APPLIED TO A DISCUSSION OF VARIABLE BINDING
Richard Rohwer

States or state sequences in neural network models are made to
represent concepts from applications. This paper motivates, introduces
and discusses a formalism for denoting such representations; a
representation for representations.  The formalism is illustrated by
using it to discuss the representation of variable binding and
inference abstractly, and then to present four specific
representations. One of these is an apparently novel hybrid of phasic
and tensor-product representations which retains the desirable
properties of each.

HOW MANY THOUGHTS CAN YOU THINK?
Richard Rohwer

In ordinary computer programmes, the relationship between data in
a machine and the concepts it represents is defined arbitrarily 
by the programmer.  It is argued here that the Strong AI hypothesis
suggests that no such arbitrariness is possible in the relationship
between brain states and mental experiences, and that this may place
surprising limitations on the possible variety of mental experiences.

Possible psychology experiments are sketched which aim to falsify
the Strong AI hypothesis by indicating that these limits can be
exceeded.  It is concluded that although such experiments might
be valuable, they are unlikely to succeed in this aim.
