Jeff Hawkins and Marcus Lewis on Grid Cell Oscillators - February 3, 2021
Channel: Numenta
Date: 2021-02-05

Building upon his prior grid cell model, Marcus Lewis explores ways to transform an array of 1D grid cell oscillators to 2D grid cell modules. He evaluates and explains one possible deterministic mapping technique that could be used to achieve this. 

In the second part, Jeff Hawkins attempts to explain the physical structure of minicolumns and how they might interact.  He proposes a new mechanism that introduces the idea of a voltage controlled oscillator in dendrites for dimensional movement in grid cells. With this mechanism, the grid cell will represent much more complex interactions and could possibly explain how the cells make connections to each other.

Numenta is leading the new era of machine intelligence. Our deep experience in theoretical neuroscience research has led to tremendous discoveries on how the brain works. We have developed a framework called the Thousand Brains Theory of Intelligence that will be fundamental to advancing the state of artificial intelligence and machine learning. By applying this theory to existing deep learning systems, we are addressing today’s bottlenecks while enabling tomorrow’s applications.
