Patent ID: 8543526

Claim:
A system comprising: a physical processor; and physical storage media, the physical processor and physical storage media being configured to implement: a filter configured to create a feature vector from an input signal, wherein elements of the feature vector correspond to individual frequency bands of the input signal, wherein one or more individual elements of the feature vector correspond to adjacent individual frequency bands of the input signal; a feed-forward set of neuron groups implemented using the physical processor and physical storage media, wherein the feed-forward set of neuron groups is configured to enhance activity within a stimulated frequency band and attenuate activity surrounding the stimulated frequency band, wherein the stimulated frequency band corresponds to a particular element of the feature vector, wherein a radius of individual frequency bands are adjacent to the stimulated frequency band, and wherein the individual frequency bands that are outside of the radius of individual frequency bands are attenuated, wherein the feed-forward set of neuron groups comprise a first and second neuron group, the first neuron group feeding into the second neuron group, wherein the feed-forward set of neuron groups operate on subsequent time-slices of the input signal, wherein the first neuron group operates on a first time slice, and wherein the second neuron group operates on a second time slice; and a surround-inhibition set of neuron groups configured to further attenuate activity surrounding the stimulated frequency band.
