[Chicago] neural networks

[John Jacobsen]

Hi Adam,

I've done some work with NNs a long time ago - feedforward nets  
trained using backpropagation, for use in a high energy physics  
experiment at CERN.

I might be able to remember some of the details... I'd be curious to  
know what you have in mind.

Unfortunately I am out of town for this month's ChiPy, but I am happy  
to discuss over email.

John

p.s. the paper reference for the work is as follows.  I can send you  
a scanned PDF if you are interested.
