Neural Network applications using Beowulf

Hi Eray,

What you said was pretty much true until recently.  In WCCI2002 
(http://www.wcci2002.org/) this May, Dr. Hecht-Nielsen from Univeristy of 
California, San Diego, announced his new thalamocortical information 
processing theory, which, I think, is paving the way for next generation AI 
research.  In his special lecture, he showed a couple slides of 
parallel-computing machines he used in his lab.  Even though he never got 
into the details of these machines, from what i know about associative 
memory networks, which are the building blocks of his new theories, it does 
demonstrate highly parallel-implementable features.  And we are talking 
about thousands of nodes  as minimum requirements for these networks to be 
functional.

In my opinions, there are tremendous potentials for parallel computing in 
the neural network arena.  The question is what kind of practical/useful 
applications would come out of it.

Regards


Thomas Zheng
