Hi Fergal, this is great work!!, I really like the detailed and thought through describtion on http://inbits.com/2013/11/adding-prediction-to-the-nupic-spatial-pooler/
First off, I dont know where to ask, so be it ML for ideas, and GH for code.. I like the idea of unifying data structures (columns with cells) for TP and SP. My question is, what makes SP now not being the same as TP? Or is it, that SP reacts to predictive cells of a TP above, but does not make any predictions (SP's) itself? I know i real region, SP+TP are blended together, we had them separated here for sometimes only one functionality is needed. That is, how is the SPenhanced better/different than current SP+TP? I would slightly worry the performance impact for bigger workload, still this is a must have for it's bio-correctness! What makes me trouble is this quote: " The SP doesn’t know anything about TP’s. In fact, it thinks it has only one cell per column, or that a cell and a column are the same thing. That’s why it has one feedforward dendrite per column. The TP only knows about the SDR of columns, it doesn’t see inside the SP, so it can’t see any feedforward dendrites. So, if we want to do this, we have to connect the column and its cells (at least virtually). This would happen in the Region (which owns both). " Does it mean (see Q1) that SP will be bounded to a TP? I want to do work where SP, TP, encoders would mix with other parts of the system, and an SDR vector seems as the best "API" to communicate. Would that mean the new implementation would be unusable there?
