Marcus Lewis reviews the paper “The Tolman-Eichenbaum Machine: Unifying Space and Relational Memory through Generalization in the Hippocampal Formation” 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.
