Adding Lateral Inhibition to a Simple Feedforward Network Enables It to Perform Exclusive-Or
Article PDF (40.13 KB)
Abstract

A simple laterally inhibited recurrent network that implementse xclusive-or is demonstrated. The network consists of two mutually inhibitory units with logistic output function, each receiving one external input and each connected to a simple threshold output unit. The mutually inhibitory units settle into a point attractor. We investigate the range of steepness of the logistic and the range of inhibitory weights for which the network can perform exclusive-or.
