Sigmoid Neural Transfer Function Realised by Percolation

Pignon, D., Parmiter, P.J.M., Slack, J.K., Hands, M.A., Hall, T.J., Daalen, M. and Shawe-Taylor, J. (1996) Sigmoid Neural Transfer Function Realised by Percolation Optics Letters, 21, (3), pp. 222-224.

Record type: Article


An experiment using the phenomenon of percolation has been conducted to demonstrate the implementation of neural functionality (summing and sigmoid transfer). A simple analog approximation to digital percolation is implemented. The device consists of a piece of amorphous silicon with stochastic bit-stream optical inputs, in which a current percolating from one end to the other defines the neuron output, also in the form of a stochastic bit stream. Preliminary experimental results are presented.
