Abstract

We have mapped the contrastive divergence learning scheme of the Product of Experts (PoE) onto electrical circuits. The issues raised during that hardware translation are discussed in this paper and some circuits presenting our solutions described. The entire learning rule is implemented in mixed-signal VSLI on a 0.6μm CMOS process. Chips results validating our approach and methodology are also presented.
