High-Contrast Reflection Tomography with Total-Variation Constraints
Ajinkya Kadu, Hassan Mansour, Petros T. Boufounos
Inverse scattering is the process of estimating the spatial distribution of the scattering potential of an object by measuring the scattered wavefields around it. In this paper, we…
On the modes of convergence of Stochastic Optimistic Mirror Descent (OMD) for saddle point problems
Yanting Ma, Shuchin Aeron, Hassan Mansour
In this article, we study the convergence of Mirror Descent (MD) and Optimistic Mirror Descent (OMD) for saddle point problems satisfying the notion of coherence as proposed in Mer…
CDSA: Cross-Dimensional Self-Attention for Multivariate, Geo-tagged Time Series Imputation
Jiawei Ma, Zheng Shou, Alireza Zareian +3
Many real-world applications involve multivariate, geo-tagged time series data: at each location, multiple sensors record corresponding measurements. For example, air quality monit…
Recovery Analysis of Damped Spectrally Sparse Signals and Its Relation to MUSIC
Shuang Li, Hassan Mansour, Michael B. Wakin
One of the classical approaches for estimating the frequencies and damping factors in a spectrally sparse signal is the MUSIC algorithm, which exploits the low-rank structure of an…
Sparse Blind Deconvolution for Distributed Radar Autofocus Imaging
Hassan Mansour, Dehong Liu, Ulugbek S. Kamilov +1
A common problem that arises in radar imaging systems, especially those mounted on mobile platforms, is antenna position ambiguity. Approaches to resolve this ambiguity and correct…
Online Detection of Action Start in Untrimmed, Streaming Videos
Zheng Shou, Junting Pan, Jonathan Chan +5
We aim to tackle a novel task in action detection - Online Detection of Action Start (ODAS) in untrimmed, streaming videos. The goal of ODAS is to detect the start of an action ins…
