I’ve a question about HTM algorithm (based on the one described in paper: A Theory of How Columns in the Neocortex Enable Learning the Structure of the World). Here we want to present an hierarchical model which has at least two set of columns(the output of a column A in first set can be source of input for a column B in second set). The proximal input and basal input for input layer in A can be provided by us(we can use encoders to encode real world data or otherwise). But what is proximal input and basal input for input layer in B? Is proximal input for input layer in B come from the output layer in A? So how about basal input, which works as location signal? ---
