Hi Aseem,
The grannies idea came from the go-back to the bits idea, which I believe the
Numenta guys call "reconstruction". That strategy did not use cells and reverse
dendrites, but a procedural equivalent. They'll tell you why this was abandoned
in favour of the lookup tables for Grok.
Regards,
Fergal Byrne
