Marcus Lewis reviews the paper “The Tolman-Eichenbaum Machine” by James Whittington, et al… He first connects and compares the paper to the grid cell module in Numenta’s “Locations in the Neocortex” paper. Marcus then gives a high-level summary of the paper and highlights two aspects - how grid cells and place cells interact, and how place cells can represent novel sensory-location pairs. The team then discusses the multiple grid cell modules and mechanisms presented in the paper.
