Some details murky on temporal implementation

Can I assume that every cell starts off with say - 20 dendrite segments?

I don’t think the TM starts off with any distal segments. They grow as learning occurs. How many segments per cell seems to depend on the complexity of the input data.

@gidmeister

In my implementation, a synapse stores 3 pieces of information - a pointer to the presynaptic cell, a pointer to the segment it belongs to, and a permanence value.

That seems right. I’m not certain exactly how we keep this info in memory, but there’s been some conversation about the best way to group these associations recently:

HTM process optimizations

When implementing the multi-layer interactions needed for the new sensory-motor functions, I found that I had coded myself into a corner with HTM.js. The way I implemented the process makes it very difficult for more than one layer to interact with each other at different steps of the process. As a result I am refactoring. Since HTM.js needs to be as lightweight as possible (designed to run in a browser), I thought I would take the opportunity to discuss and possibly implement some optimizati…
