Title:       Multiresolution Matrix Factorization

Abstract:

Matrices that appear in modern data analysis and machine learning problems
often exhibit complex hierarchical structure, which goes beyond what can be
uncovered by traditional linear algebra tools, such as eigendecomposition.
In this talk I describe a new notion of matrix factorization inspired by
multiresolution analysis that can capture structure in matrices at multiple
different scales. The resulting Multiresolution Matrix Factorizations
(MMFs) not only provide a wavelet basis for sparse approximation, but can
also be used for matrix compression and as a prior for matrix completion.

The work presented in this talk is joint with Nedelina Teneva and Vikas
Garg.
