Optical implementation of localized interconnected neural network

Abstract

The localized interconnected neural network (LINN) provides for a smaller interconnection weight matrix (IWM). It is possible to construct a large‐scale optical neural network using commercially available spatial light modulators (SLMs). In this article, optical implementation of one‐dimensional (ID) LINN for associative memory is discussed, in which three optoelectronic architectures are proposed. In the proposed optoelectronic correlation system, the IWM is generated by a TV monitor, while input data are displayed on a liquid crystal television (LCTV). Experimental demonstrations are also provided. © 1993 John Wiley & Sons, Inc.
