OCCAM (Orifice-Controlled Canister Munition) Quarterly R/D Status Report (3rd): December 1986-February 1987

Abstract

Bart wrote three full-length technical papers during Qtr 3: Fuzzy Associative Memories, Hidden Patterns in Combined Knowledge Networks, and, with Clark Guest, Optical Bidirectional Associative Memories. Extensive fuzzy cognitive map (FCM) limit cycle stability experiments were performed. Simulation of an all-optical continuous Cohen-Grossberg symmetric undirectional autoassociator model as an optical continuous BAM precursor began. Supervised learning (backpropagation) experiment with scale and rotation invariance models of image recognition was performed. Work on holographic association of phase- encoded images in photorefractive materials (lithium niobate) began. Correlation of (two-wave mixed) pattern images using barium titanate in a reflective pumping arrangement was demonstrated. Keywords: Resonators, Fuzzy entropy, Neural networks, Adaptive resonance.
