Spatial Power Estimation via Riemannian Covariance Matching
Or Cohen, Alon Amar, Ronen Talmon
We propose a new method for spatial power spectrum estimation in array processing that leverages the Riemannian geometry of Hermitian positive definite (HPD) matrices. We show that…

Geometric Mode-Selection Scores for Delay-Coordinates Dynamic Mode Decomposition
Yoav Harris, Hadas Benisty, Ronen Talmon
Delay-coordinates dynamic mode decomposition (DC-DMD) is widely used to extract coherent spatiotemporal modes from high-dimensional time series. A central challenge is distinguishi…
