Analogue Memory Mechanisms for Neural Nets
Abstract
The need for a component capable of simulating semi-permanent changes in biological neurons, suitable for inclusion in brain models, and in perceptrons in particular, is discussed. Various devices intended for this purpose are reviewed and evaluated. A novel method of flux integration, using a permalloy wire as the flux storing medium, and the voltage induced in a search coil as the result of magnetostriction in the wire for readout, is described in detail. The design procedure for the complete memory of an audio-perceptron, Tobermory, based on the magnetostrictive readout integrator, is outlined. Modifications in the integrator, intended to render it suitable for larger and topologically more sophisticated models, are anticipated.
