Inhibition Mechanisms in Spatial Pooling

Animation of spatial pooler and temporal memory

I’ve just implemented a HTM region in JS. Although its not perfect I thought I’d share an animation that I think helps illustrate the learning process in the region. It is a very simple repeating alternating input pattern. The top row is the input space. The cells in the columns span vertically. The proximal connections are a generalized sum of segment connections. Red is active, and yellow is predictive. From the start the columns are bursting. As the columns compete, different sets of column…
