Seminar

ISTC Seminar: Manifold and Semi-supervised Learning Using Laplace Operators

Mikhail Belkin
Department of Compter Science and Engineering, The Ohio State University

In this talk I will discuss our work on manifold learning and its applications to data representation, semi-supervised and unsupervised learning. In particular, I will discuss the significance of the Laplace operator on the manifold and its connections to the heat diffusions. I will show some theoretical results on reconstructing Laplace operators and their eigenfunctions from point-cloud data and various applications, particularly to dimensionality reduction and semi-supervised learning.
