Episode 1: Research Update with Jeff Hawkins - Part 1

In this in-depth interview with Numenta Co-founder Jeff Hawkins, host Matt Taylor dives deeply into concepts of location and object representation in the neocortex. In Part 1 of this 2-part interview, they discuss location, unique spaces, object compositionality & behavior, movement and learning, sequence memory, and the definition of “space” itself. In Part 2, they have an in-depth discussion on how HTM sequence memory builds object representations in space through movement.

For educational material regarding the topics discussed in this podcast episode, you have a few options. If you want to be fed the theory, watch HTM School. If you need more details, there are many papers to explore. If you want to talk to others about HTM theory, get involved in our community. For a primer on grid cells, have a look at this interactive blog post. For more on how we think grid cells work within the neocortex, watch Jeff’s recent talk, Does the Neocortex Use Grid Cell-Like Mechanisms to Learn the Structure of Objects?
