SPEAKER: Risi Kondor - University of Chicago
TITLE: Multiresolution Matrix Factorization
Matrices that appear in modern data analysis and machine learning problems
often have complex hierarchical structures that go beyond what can be
uncovered by traditional linear algebra tools, such as eigendecompositions.
Inspired by ideas from multiresolution analysis, we introduce a new notion
of matrix factorization 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 was done jointly with Nedelina Teneva and
Program in Applied & Computational Mathematics
