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.…
Riemannian Covariance Fitting for Direction-of-Arrival Estimation
Joseph S. Picard, Amitay Bar, Ronen Talmon
Covariance fitting (CF) is a comprehensive approach for direction of arrival (DoA) estimation, consolidating many common solutions. Standard practice is to use Euclidean criteria f…
The Expected Loss of Preconditioned Langevin Dynamics Reveals the Hessian Rank
Amitay Bar, Rotem Mulayoff, Tomer Michaeli +1
Langevin dynamics (LD) is widely used for sampling from distributions and for optimization. In this work, we derive a closed-form expression for the expected loss of preconditioned…
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…
Option Discovery in the Absence of Rewards with Manifold Analysis
Amitay Bar, Ronen Talmon, Ron Meir
Options have been shown to be an effective tool in reinforcement learning, facilitating improved exploration and learning. In this paper, we present an approach based on spectral g…
