On Bounds for Greedy Schemes in String Optimization based on Greedy Curvatures

no code implementations10 Apr 2024 Bowen Li, Brandon Van Over, Edwin K. P. Chong, Ali Pezeshki

We prove that our bound is superior to the greedy curvature bound of Conforti and Cornu\'ejols.

Subspace Perturbation Analysis for Data-Driven Radar Target Localization

no code implementations14 Mar 2023 Shyam Venkatasubramanian, Sandeep Gogineni, Bosung Kang, Ali Pezeshki, Muralidhar Rangaswamy, Vahid Tarokh

Via the use of space-time adaptive processing (STAP) techniques and convolutional neural networks, these data-driven approaches to target localization have helped benchmark the performance of neural networks for matched scenarios.

Minimax Concave Penalty Regularized Adaptive System Identification

no code implementations7 Nov 2022 Bowen Li, Suya Wu, Erin E. Tripp, Ali Pezeshki, Vahid Tarokh

We develop a recursive least square (RLS) type algorithm with a minimax concave penalty (MCP) for adaptive identification of a sparse tap-weight vector that represents a communication channel.

Data-Driven Target Localization Using Adaptive Radar Processing and Convolutional Neural Networks

no code implementations7 Sep 2022 Shyam Venkatasubramanian, Sandeep Gogineni, Bosung Kang, Ali Pezeshki, Muralidhar Rangaswamy, Vahid Tarokh

Leveraging the advanced functionalities of modern radio frequency (RF) modeling and simulation tools, specifically designed for adaptive radar processing applications, this paper presents a data-driven approach to improve accuracy in radar target localization post adaptive radar detection.

Toward Data-Driven STAP Radar

no code implementations26 Jan 2022 Shyam Venkatasubramanian, Chayut Wongkamthong, Mohammadreza Soltani, Bosung Kang, Sandeep Gogineni, Ali Pezeshki, Muralidhar Rangaswamy, Vahid Tarokh

In this regard, we will generate a large, representative adaptive radar signal processing database for training and testing, analogous in spirit to the COCO dataset for natural images.

Bayesian Learning of Occupancy Grids

no code implementations18 Nov 2019 Christopher Robbiano, Edwin K. P. Chong, Mahmood R. Azimi-Sadjadi, Louis L. Scharf, Ali Pezeshki

Occupancy grids encode for hot spots on a map that is represented by a two dimensional grid of disjoint cells.

Hypothesis Testing in Feedforward Networks with Broadcast Failures

no code implementations19 Nov 2012 Zhenliang Zhang, Edwin K. P. Chong, Ali Pezeshki, William Moran

In the case where the flipping probabilities converge to 1/2, we derive a necessary condition on the convergence rate of the flipping probabilities such that the decisions still converge to the underlying truth.
