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.
