Title:          *      **Learning from Labeled and Unlabeled Data, Global
vs. Multiscale Approaches*


In recent years there is increasing interest in learning from both labeled
and unlabeled data (a.k.a. semi-supervised learning, or SSL). The key
assumption in SSL, under which an abundance of unlabeled data may help, is
that there is some relation between the unknown response function to be
learned and the marginal density of the predictor variables.

In the first part of this talk I'll present a statistical analysis of two
popular graph based SSL algorithms: Laplacian regularization method and
Laplacian eigenmaps.

In the second part I'll present a novel multiscale approach for SSL as well
as supporting theory. Some intimate connections to harmonic analysis on
abstract data sets will be discussed.

Joint work with Nati Srebro (TTI), Xueyuan Zhou (Chicago), Matan Gavish
(WIS/Stanford) and Ronald Coifman (Yale).
