I wanted to talk a bit about using topology with HTM. Most of this is just me working these thoughts out in my head, so some of it might be confusing or inaccurate. I welcome feedback and discussion. With no topology …

I am studying the HTM course. What if we use a topological HTM region to classify pictures? How is the effect? Is there any experiment?

I would start a new thread to discuss ideas on how to use attractors to distill topology from semantics. This for example could be relevant in an implementation of semantic-folding. . I’ll start the conversation with …

I've obviously been thinking a lot about topology lately. One of my interesting finds is that we really don't have any good examples of encoders taking advantage of topology. The closest I got was streaming a loop of ani…

I'm starting to experiment with topology so I can talk about local inhibition in the next HTM School. I see that some columns getting no overlap with the input space are being activated. I think this has something to do …
