1. A method for feature extraction, comprising: generating synaptic connectivity information for a neurosynaptic core circuit, wherein the core circuit comprises one or more electronic neurons, one or more electronic axons, and an interconnect fabric including a plurality of synapse devices for interconnecting said one or more electronic neurons with said one or more electronic axons; initializing said interconnect fabric based on the synaptic connectivity information generated; receiving input via said one or more electronic axons; and extracting a set of features from the input received, wherein the set of features extracted comprises a set of features with reduced correlation.
