Partial Trace Regression and Low-Rank Kraus Decomposition

ICML 2020poster

The trace regression model, a direct extension of the well-studied linear regression model, allows one to map matrices to real-valued outputs. We here introduce an even more general model, namely the partial-trace regression model, a family of linear mappings from matrix-valued inputs to matrix-valu…

Multi-view Metric Learning in Vector-valued Kernel Spaces

AISTATS 2018poster

We consider the problem of metric learning for multi-view data and present a novel method for learning within-view as well as between-view metrics in vector-valued kernel spaces, as a way to capture multi-modal structure of the data. We formulate two convex optimization problems to jointly learn the…
