Exact-Penalty Prox-Linear Methods for Bilevel Optimization with Lower-Level Gradient Penalty
Yutong Zheng, Jiani Li, Qingna Li
Bilevel optimization is a fundamental framework for hierarchical decision-making, but its solution is challenging due to the implicit and typically set-valued nature of the lower-l…
Joint Training Scattering Matrix Learning and Channel Estimation for Beyond-Diagonal Reconfigurable Intelligent Surfaces
Yiyang Peng, Binggui Zhou, Yutong Zheng +2
Beyond-diagonal reconfigurable intelligent surface (BD-RIS) generalizes the conventional diagonal RIS (D-RIS) by introducing tunable inter-element connections, offering enhanced wa…
Bilevel Models for Adversarial Learning and A Case Study
Yutong Zheng, Qingna Li
Adversarial learning has been attracting more and more attention thanks to the fast development of machine learning and artificial intelligence. However, due to the complicated str…
Detecting subtle macroscopic changes in a finite temperature classical scalar field with machine learning
Jiming Yang, Yutong Zheng, Jiahong Zhou +2
The ability to detect macroscopic changes is important for probing the behaviors of experimental many-body systems from the classical to the quantum realm. Although abrupt changes…
