Geometric Aspects of Learning from Labeled and Unlabeled Data

Dr. Misha Beylkin, Professor of Computer Science
Ohio State University

Dr. Misha Beylkin spoke on Friday, March 16th, 2007 at 1:00PM in Engineering Building 2, Room 1230

While inference from labeled data is one of the traditional problems of
machine learning and statistics, it is only recently that we have
developed an understanding of how unlabeled data may be helpful in
various inferential problems. It turns out that many aspects of the
connection between labeled and unlabeled data can be interpreted

In this talk I will discuss certain geometric invariants, centered
around the notions of the Laplace operator and the heat equation, and
their role in machine learning. I will also discuss theoretical results
on reconstructing these objects from sampled data, as well as some
recent applications of these ideas to computing volumes of convex bodies
in polynomial time.
