Let be a complete Riemannian manifold and a probability measure on . Assume . We derive a new bound (in terms of , the injectivity radius of and an upper bound on the sectional curvatures of ) on the… Expand

We investigate the sensitivity of the problem of nonorthogonal (matrix) joint diagonalization (NOJD), which is closely related to the issue of uniqueness in tensor decompositions.Expand

We study the convergence of constant step-size gradient descent algorithms for solving the problem of finding the global Riemannian center of mass of a set of data points on a Riemanian manifold.Expand

Processing of manifold-valued data has received considerable attention in recent years. Standard data processing methods are not adequate for such data. Among many related data processing tasks… Expand
