ABSTRACT

A physical neural network includes at least one neuron-like node that sums at least one input signal and generates at least one output signal based on a threshold associated with the at least one input signal, at least one connection network associated with the at least one neuron-like node wherein the at least one connection network comprises a plurality of interconnected connections, such that each connection of the plurality of interconnected connections is strengthened or weakened according to an application of an electric field. In some cases, the threshold can include a threshold below which the at least one output signal is not generated and above which the at least one output signal is generated.
