Pontryagin Neural Operator for Solving Parametric General-Sum Differential Games

no code implementations3 Jan 2024 Lei Zhang, Mukesh Ghimire, Zhe Xu, Wenlong Zhang, Yi Ren

To address these challenges, we propose in this paper a Pontryagin-mode neural operator that outperforms existing state-of-the-art (SOTA) on safety performance across games with parametric state constraints.

Value Approximation for Two-Player General-Sum Differential Games with State Constraints

1 code implementation28 Nov 2023 Lei Zhang, Mukesh Ghimire, Wenlong Zhang, Zhe Xu, Yi Ren

Solving Hamilton-Jacobi-Isaacs (HJI) PDEs numerically enables equilibrial feedback control in two-player differential games, yet faces the curse of dimensionality (CoD).

Recon: Reducing Conflicting Gradients from the Root for Multi-Task Learning

1 code implementation22 Feb 2023 Guangyuan Shi, Qimai Li, Wenlong Zhang, Jiaxin Chen, Xiao-Ming Wu

Our experiments show that such a simple approach can greatly reduce the occurrence of conflicting gradients in the remaining shared layers and achieve better performance, with only a slight increase in model parameters in many cases.

Recent quadrotors have transcended conventional designs, emphasizing more on foldable and reconfigurable bodies.

Approximating Discontinuous Nash Equilibrial Values of Two-Player General-Sum Differential Games

no code implementations5 Jul 2022 Lei Zhang, Mukesh Ghimire, Wenlong Zhang, Zhe Xu, Yi Ren

This paper investigates two potential solutions to this problem: a hybrid method that leverages both supervised Nash equilibria and the HJI PDE, and a value-hardening method where a sequence of HJIs are solved with a gradually hardening reward.

A Closer Look at Blind Super-Resolution: Degradation Models, Baselines, and Performance Upper Bounds

no code implementations10 May 2022 Wenlong Zhang, Guangyuan Shi, Yihao Liu, Chao Dong, Xiao-Ming Wu

The recently proposed practical degradation model includes a full spectrum of degradation types, but only considers complex cases that use all degradation types in the degradation process, while ignoring many important corner cases that are common in the real world.

Overcoming Catastrophic Forgetting in Incremental Few-Shot Learning by Finding Flat Minima

1 code implementation NeurIPS 2021 Guangyuan Shi, Jiaxin Chen, Wenlong Zhang, Li-Ming Zhan, Xiao-Ming Wu

Our study shows that existing methods severely suffer from catastrophic forgetting, a well-known problem in incremental learning, which is aggravated due to data scarcity and imbalance in the few-shot setting.
