Numenta is very timely, since they have been =roposing a deep learning style architecture for quite some time. Their =ierarchical Temporal Learning network builds hierarchies of feature =etectors (like everybody these days) and focuses on temporal distance =earning. On the surface, the claims are similar to =chmidhuber's/Hochreiter's LSTM (but using fewer computational =esources), and I would apply the same personal criticism: I do not =hink that the whole of the mind or brain can be explained using a =ingle unifying principle, but perhaps perception and a lot of learning =nd representation (i.e. quite a bit of the neocortex and hippocampus) =an.

I have not come across a comparative evaluation of HTM that =ould demonstrate its abilities and limitations when compared to the =ompetition. Numenta is not academic, so it is understandable that they =on't waste much time publishing, but it makes it hard for me to tell =ow far they have come. I have not seen a DeepMind style Big Demo of =heir stuff, and I could not get the open source version to work =quickly enough) when I tried. I have not talked to Jeff Hawkins =et.
