Good observations, I only disagree in a one point: > However, we can assume, can we not, that Dileep most likely continued with and expanded upon the work he was doing while part of Numenta? While his approach was certainly more "East Pole" AI that Numenta's more connectionist architecture, it too was based on biology (neocortex) as well
I'm not sube about this... From I saw in Dileep's peer-reviewed papers (some co-authored with Hawkins) the essence of the predictions was bayesian inference using matemathical formulas to perform this. The recent "connectionism" approach adopted by Numenta tries perform similar function*, but it doesn't use bayesian formulas, on the contrary: it BEHAVES in a bayesian manner, which is really NICE.. This to me is more realistic than any based-rules inference.. David PS: I sincerelly don't know who first suggested this approach, i.e. the own Dileep, Subutai, or other.. but I personally I consider this person (or people) as true genius..
