Title: Mixture Proportion Estimation for Weakly Supervised Learning

Abstract:

Weakly supervised learning has come to refer to a spectrum of problems
in machine learning, lying somewhere between supervised and unsupervised
learning, where partial or noisy label information is available in some
sense. In this talk I will overview many examples of weakly supervised
learning problems, and argue that several of them can be solved in terms
of a fundamental problem called mixture proportion estimation (MPE). MPE
is the problem of inferring the maximum proportion of one distribution
that is present in another, given random samples from each distribution.
I will discuss several approaches to MPE, including one based on the
kernel mean embedding, which exhibits state-of-the-art performance and
comes with theoretical guarantees.
