Faster Rates for the Frank-Wolfe Algorithm Using Jacobi Polynomials
Robin Francis, Sundeep Prabhakar Chepuri
The Frank Wolfe algorithm (FW) is a popular projection-free alternative for solving large-scale constrained optimization problems. However, the FW algorithm suffers from a sublinea…
Learning Sparse Graphs with a Core-periphery Structure
Sravanthi Gurugubelli, Sundeep Prabhakar Chepuri
In this paper, we focus on learning sparse graphs with a core-periphery structure. We propose a generative model for data associated with core-periphery structured networks to mode…
Joint Communication and Radar Sensing with Reconfigurable Intelligent Surfaces
R. S. Prasobh Sankar, Battu Deepak, Sundeep Prabhakar Chepuri
In this paper, we use a reconfigurable intelligent surface (RIS) to enhance the radar sensing and communication capabilities of a mmWave dual function radar communication system. T…
Self Calibration of Scalar and Vector Sensor Arrays
Krishnaprasad Nambur Ramamohan, Sundeep Prabhakar Chepuri, Daniel Fernandez Comesana +1
In this work, we consider the problem of joint calibration and direction-of-arrival (DOA) estimation using sensor arrays. This joint estimation problem is referred to as self calib…
