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…
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…
Domain Adaptation for DoA Estimation in Multipath Channels with Interferences
Amitay Bar, Joseph S. Picard, Israel Cohen +1
We consider the problem of estimating the direction-of-arrival (DoA) of a desired source located in a known region of interest in the presence of interfering sources and multipath.…
On Interference-Rejection Using Riemannian Geometry for Direction of Arrival Estimation
Amitay Bar, Ronen Talmon
We consider the problem of estimating the direction of arrival of desired acoustic sources in the presence of multiple acoustic interference sources. All the sources are located in…
Unsupervised Ensembling of Multiple Software Sensors with Phase Synchronization: A Robust Approach For Electrocardiogram-derived Respiration
Jacob McErlean, John Malik, Yu-Ting Lin +2
Objective: We aimed to fuse the outputs of different electrocardiogram-derived respiration (EDR) algorithms to create one EDR signal that is of higher quality. Methods: We viewed e…
