Robust Broadband Beamforming using Bilinear Programming
Nakul Singh, Coleman DeLude, Mark A. Davenport +1
We introduce a new method for robust beamforming, where the goal is to estimate a signal from array samples when there is uncertainty in the angle of arrival. Our method offers sta…
Perceptual adjustment queries and an inverted measurement paradigm for low-rank metric learning
Austin Xu, Andrew D. McRae, Jingyan Wang +2
We introduce a new type of query mechanism for collecting human feedback, called the perceptual adjustment query ( PAQ). Being both informative and cognitively lightweight, the PAQ…
Distance preservation in state-space methods for detecting causal interactions in dynamical systems
Matthew O'Shaughnessy, Mark Davenport, Christopher Rozell
We analyze the popular ``state-space'' class of algorithms for detecting casual interaction in coupled dynamical systems. These algorithms are often justified by Takens' embedding…
Learned Proximal Operator for Solving Seismic Deconvolution Problem
Peimeng Guan, Naveed Iqbal, Mark A. Davenport +1
Seismic deconvolution is an essential step in seismic data processing that aims to extract layer information from noisy observed traces. In general, this is an ill-posed problem wi…
Dynamic matrix recovery from incomplete observations under an exact low-rank constraint
Liangbei Xu, Mark A. Davenport
Low-rank matrix factorizations arise in a wide variety of applications -- including recommendation systems, topic models, and source separation, to name just a few. In these and ma…
