Abstract:

         The problem of optimizing a non-smooth function over the Stiefel manifold arises in many machine learning and signal processing applications. This naturally calls for the design of practically efficient iterative methods with good convergence guarantees for solving this class of problems. In this talk, we will survey some recent progress in this direction and discuss some open questions for further research.
