Interesting perspective, @sunguralikaan. Thanks for sharing your experience.
[quote="sunguralikaan, post:9, topic:3000"] Almost everytime it did not converge onto an actual activation that happened as @jakebruce said. It contained bits and pieces from multiple activations which was very hard to utilize in a meaningful way. [/quote] I wonder if a single activation for a high order prediction is really always the "correct" answer here. I think it depends on the question that is being asked. In situations where multiple simultaneous sequences are known, from a given point in time the system rightfully <b>does not know</b> which sequence is going to continue. It'll ideally only have some idea of the frequency of patterns which you might interpret as their probability of occurring. So, you can ask the system different things here. You could ask it "what do you think is the most likely activation to occur at time step t+n where n>1, or, alternatively, you could ask it for everything that it thinks <i>could</i> happen which would best be represented as a union of activations which individually represent possible futures. In both cases, I imagine the predictions are going to get less reliable the farther out you go. In the case of the single activation, the single activation prediction is going to be less reliable due to the number of possible answers blowing up exponentially leading to more uncertainty. In the case of a union of possible futures, the farther out you go the denser the SDR is going to become because you're unioning so many possible futures. The resulting dense SDR is then rendered uninformative as you go further out. In any case, if it's still accessible, would you mind sharing your code that you used to tie cellular activation predictions back to the TM algorithm? I'd be very interested to see your approach to do this from an implementation standpoint.
