Paper Abstract

We describe recent results for implementation of the backpropagation neural network on an experimental optical neurocomputer developed under ARPA sponsorship. Weights are stored holographically in a photorefractive crystal using a recording method which eliminates crosstalk due to Bragg degeneracy and permits full utilization of the input and output. Experimental results are discussed for handwritten digit recognition.
