Abstract:

This report summarizes research efforts on 1 the demonstration of holographic degeneracies in associative memories, 2 the procedure for designing fractal grids for planar holograms, 3 the experimental demonstration of one and two layer neural networks that are designed with such fractal sampling grids, 4 the experimental demonstration of dynamic holographic memories that are capable of an arbitrarily long sequence of adaptations, 5 the optical implementation of the Kanervas network for hand-written character recognition, 6 the development of an anti-Hebbian local learning algorithm for training multi-layer neural networks, 7 the experimental demonstration of optical radial basis function network, and 8 the demonstration of a two-layer local-representation optical network for real-time face recognition.
