Optimal Parseval frames: Total coherence and total volume
Jameson Cahill, Peter G. Casazza
We introduce three quantities called total coherence, total volume, and nuclear energy, and we show that equiangular Parseval frames maximize all three of these quantities over the…

Complete set of translation invariant measurements with Lipschitz bounds
Jameson Cahill, Andres Contreras, Andres Contreras Hip
In image and audio signal classification, a major problem is to build stable representations that are invariant under rigid motions and, more generally, to small diffeomorphisms. T…
