Abstract

This paper describes the development of a new technique for determining the weights of a Volterra Connectionist Model (VCM) applied to the classification of stationary time series. This involves assigning a classification index to each class of time series and developing expressions for the state conditional probability density functions such that the Bayes Risk can be expressed as a function of the weights. The optimal weight values then correspond to the minimum Bayes Risk.
