Towards Assessing the Synthetic-to-Measured Adversarial Vulnerability of SAR ATR

1 code implementation30 Jan 2024 Bowen Peng, Bo Peng, Jingyuan Xia, Tianpeng Liu, Yongxiang Liu, Li Liu

Recently, there has been increasing concern about the vulnerability of deep neural network (DNN)-based synthetic aperture radar (SAR) automatic target recognition (ATR) to adversarial attacks, where a DNN could be easily deceived by clean input with imperceptible but aggressive perturbations.

Meta-learning Based Beamforming Design for MISO Downlink

no code implementations25 Jan 2021 Jingyuan Xia, Gunduz Deniz

Downlink beamforming is an essential technology for wireless cellular networks; however, the design of beamforming vectors that maximize the weighted sum rate (WSR) is an NP-hard problem and iterative algorithms are typically applied to solve it.

Meta-learning based Alternating Minimization Algorithm for Non-convex Optimization

1 code implementation9 Sep 2020 Jingyuan Xia, Shengxi Li, Jun-Jie Huang, Imad Jaimoukha, Deniz Gunduz

In this paper, we propose a novel solution for non-convex problems of multiple variables, especially for those typically solved by an alternating minimization (AM) strategy that splits the original optimization problem into a set of sub-problems corresponding to each variable, and then iteratively optimize each sub-problem using a fixed updating rule.
