Abstract: I will start by discussing the problem of finding a low rank approximation to a (perhaps large) matrix. I will describe a fast and provably accurate randomized method. I will then turn to ongoing work on simultaneously clustering the columns of the matrix into (not so many) blocks and finding a low rank approximation to each block.
