Jeff Hawkins on Object Modeling in the Thousand Brains Theory (Part One) - September 3, 2021
Channel: Numenta
Date: 2021-09-20

In continuation of the last two meetings where Subutai discussed voting in the Thousand Brains Theory, Jeff looks at the overall theory and focuses on the missing elements - things we haven't implemented, things that have changed due to new insights or things that are still unknown.
 
He first presents the two core ideas proposed in our Columns paper (2017), and then walks through a list of shortcomings of the hypotheses and simulation. He then gives an overview of our Frameworks paper (2019) where we hypothesized that objects are modeled based on grid cell modules. He highlights how the paper solved a few issues in the Columns paper but points out that there are still previous shortcomings and problems that we haven't addressed.
 
He wraps up the meeting by discussing the ways we’re currently trying to address these problems in our research. He proposes new ways of thinking about how we model objects, how cells represent location and orientation of the sensor and how columns detect movements and path integration. He expands these ideas further in the next meeting.

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.
