We use mean-field theory methods from Statistical Mechanics to derive the "softmax" nonlinearity from the discontinuous winner-take-all (WTA) mapping. We give two simple ways of implementing "softmax" as a multiterminal network element. One of these has a number of important network-theoretic properties. It is a reciprocal, passive, incrementally passive, nonlinear, resistive multiterminal element with a content function having the form of information-theoretic entropy. These properties should… Expand
