Abstract :
A unipolar terminal-attractor-based neural associative memory (TABAM) system with adaptive threshold and perfect convergence is presented. By adaptively setting the threshold values for the dynamic iteration for the unipolar binary neuron states with terminal attractors and an inner-product approach, it is demonstrated by means of computer simulation that perfect convergence and correct retrieval can be achieved. The simulation is completed with a small number of stored states (M) and a small number of neurons (N) but a large M/N ratio. An experiment with exclusive-OR logic operation using LCTV (liquid-crystal TV) SLM (spatial light modulators) is used to show the feasibility of the optoelectronic implementation of the models
