I found 3 talks from 2020 on your tube on a hypothetical idea of mini columns that Jeff Hawkins was working on. Here’s a screen shot a slide form two of the videos:
Thanks for bringing these back to the fore. I had forgotten about them and its good to be reminded of the theoretical work.
They haven’t done a lot of recorded discussions for a couple years so its not clear where they are on the theory. They’ve also devoted a lot of effort to applying their tech to Deep Learning so there might be a lot less theory than there used to be.
Re-reading these slides, I struck by how much I hate Numenta’s use of the word “spatial” since its never clear what they mean and it kind of conflicts with my intuition of Euclidean space.
