I was wondering if anybody is aware of any work done on holographic paradigms
in neural nets.  Of course I am aware of work done in the late 60s and early
70s by such people as Westlake, Gabor, and Pribram, and of recent work
implementing *optic* systems for heteroassociative recall and for (this
amuses me) interconnecting traditional connectionist nets.  However, noone
seems ever to have actually simulated neural holographic heteroassociative
memory and, as far as I can tell, nobody is even trying.  Given the well-known
shortcomings of back-propagation and the advantages of a holographic paradigm
(truly distributed representation, invariance, high capacity) this surprises me.
Why is this aspect of neural net research not benefiting from the recent
explosion of interest in neural systems??????????
