Low-rank approximation of parameter-dependent matrices via CUR decomposition

A low-rank approximation of a parameter-dependent matrix A(t) is an important task in the computational sciences appearing for example in dynamical systems and compression of a series of images. In this work, we introduce AdaCUR, an efficient algorithm for computing a low-rank approximation of param...
