Design and specification of analog artificial neural network

Abstract

In this paper, we have implemented, using Matlab Simulink an analog artificial neural network for breast cancer classification. Simulated results with ideal building blocks exhibit a total error of classification of 2.6%. Thanks to this value, we have modified Simulink models of the building blocks (i.e. multiplier, activation function and its derivative) in order to take into account their non-idealities. This study allows to determine their influence on the classification quality and to extract some specifications of these building blocks.
