Claim One:
1. A feature extraction method, said method comprising: presenting an input data stream to a synaptic matrix of a plurality of Anti-Hebbian and Hebbian nodes associated with an Anti-Hebbian and Hebbian module that operates a plasticity rule via an evaluate phase cycle and a feedback phase cycle; modulating a bias input line such that a bias weight does not receive a Hebbian portion of a weight update during said feedback phase in order to prevent occupation of a null state; partitioning an input space with respect to said input data stream when said plurality of Anti-Hebbian and Hebbian nodes falls randomly into an attractor state; and providing an output of said Anti-Hebbian and Hebbian module that forms a stable bit pattern as an input to a content-addressable memory for generating a maximally efficient binary label.
