Скачать или смотреть 'Eigen-view' on Grid Cells - September 21, 2020

In this week’s research meeting, Marcus Lewis presents his ‘Eigen-view’ on grid cells and connects ideas in 3 underlying papers to Numenta’s research. He discusses the mapping of grid cells in terms of eigenvectors, and evaluates eigenvectors in terms of the Fourier transform (space) and the non-Fourier transform, called “spectral graph theory” (2D graph).

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 cohesive theory, core software technology, and numerous software applications all based on principles of the neocortex. Our innovative work delivers breakthrough capabilities and demonstrates that a computing approach based on biological learning principles can do things that today’s programmed computers cannot do.
