Probabilistic frames: An overview
Martin Ehler, Kasso A. Okoudjou
Finite frames can be viewed as mass points distributed in -dimensional Euclidean space. As such they form a subclass of a larger and rich class of probability measures that we c…
Schroedinger Eigenmaps for the Analysis of Bio-Medical Data
Wojciech Czaja, Martin Ehler
We introduce Schroedinger Eigenmaps, a new semi-supervised manifold learning and recovery technique. This method is based on an implementation of graph Schroedinger operators with…
Random Tight Frames
Martin Ehler
We introduce probabilistic frames to study finite frames whose elements are chosen at random. While finite tight frames generalize orthonormal bases by allowing redundancy, indepen…
Minimization of the Probabilistic p-frame Potential
Martin Ehler, Kasso A. Okoudjou
We investigate the optimal configurations of n points on the unit sphere for a class of potential functions. In particular, we characterize these optimal configurations in terms of…
