On Structural Decompositions of Finite Frames
Alice Z. -Y. Chan, Martin S. Copenhaver, Sivaram K. Narayan +2
A frame in an -dimensional Hilbert space is a possibly redundant collection of vectors that span the space. A tight frame is a generalization of an orth…
Factor posets of frames and dual frames in finite dimensions
Kileen Berry, Martin S. Copenhaver, Eric Evert +4
We consider frames in a finite-dimensional Hilbert space where frames are exactly the spanning sets of the vector space. A factor poset of a frame is defined to be a collection of…
Characterization of the equivalence of robustification and regularization in linear and matrix regression
Dimitris Bertsimas, Martin S. Copenhaver
The notion of developing statistical methods in machine learning which are robust to adversarial perturbations in the underlying data has been the subject of increasing interest in…
