I thought that you asked and answered the efficiency question on an earlier thread:

Local inhibition instead of explicit k-winner for spatial pooler

Hello all, as much as I like the local learning rules and biological plausibility of HTM as much I dislike the explicit k-winner approach it uses to determine the minicolumns which should be used for learning. It is neither a biologically plausable implementation nor is it well suited to be ported to a GPU (which is currently my concern) as it requires either sorting or k-times some sort of max-masking. Clearly the cortex accomplishes the feat of sparse activation differently and most likely b…
