12. The storage medium of claim 11 , wherein the defined similarity metric is a Euclidean distance metric.
11. The storage medium of claim 10 , wherein program code for the spatial pooler further comprises: program code for determining, for each of the second set of one or more sensed input patterns, at least a first similarity value based on at least a first spatial co-occurrence pattern and a defined similarity metric; and program code for determining the set of spatial co-occurrence patterns based on the at least a first similarity value.
