Small Covers for Near-zero Sets of Polynomials and Learning Latent Variable Models
Offered By: IEEE via YouTube
Course Description
Overview
Explore a 25-minute IEEE conference talk on advanced statistical techniques for learning latent variable models. Delve into Gaussian Mixture Models, parameter estimation, and the Method of Moments. Examine the challenges of low degree moments and dimension reduction. Investigate the use of higher moments and zero sets in overcoming obstacles. Understand the main technical lemma and its application to cover and density estimation. Learn about mixtures of linear regressions and their implications. Gain insights from experts Ilias Diakonikolas (UW Madison) and Daniel Kane (UCSD) on small covers for near-zero sets of polynomials and their relevance to learning latent variable models.
