Automatic Reward Design via Learning Motivation-Consistent Intrinsic Rewards

no code implementations29 Jul 2022 Yixiang Wang, Yujing Hu, Feng Wu, Yingfeng Chen

In this paper, we propose to automatically generate goal-consistent intrinsic rewards for the agent to learn, by maximizing which the expected accumulative extrinsic rewards can be maximized.

DI-AA: An Interpretable White-box Attack for Fooling Deep Neural Networks

no code implementations14 Oct 2021 Yixiang Wang, Jiqiang Liu, Xiaolin Chang, Jianhua Wang, Ricardo J. Rodríguez

In this paper, we propose an interpretable white-box AE attack approach, DI-AA, which explores the application of the interpretable approach of the deep Taylor decomposition in the selection of the most contributing features and adopts the Lagrangian relaxation optimization of the logit output and L_p norm to further decrease the perturbation.

IWA: Integrated Gradient based White-box Attacks for Fooling Deep Neural Networks

no code implementations3 Feb 2021 Yixiang Wang, Jiqiang Liu, Xiaolin Chang, Jelena Mišić, Vojislav B. Mišić

To further make the perturbations more imperceptible, we propose to employ the restriction combination of $L_0$ and $L_1/L_2$ secondly, which can restrict the total perturbations and perturbation points simultaneously.

Generalizing Adversarial Examples by AdaBelief Optimizer

no code implementations25 Jan 2021 Yixiang Wang, Jiqiang Liu, Xiaolin Chang

Recent research has proved that deep neural networks (DNNs) are vulnerable to adversarial examples, the legitimate input added with imperceptible and well-designed perturbations can fool DNNs easily in the testing stage.

Multi-Agent Deep Reinforcement Learning with Adaptive Policies

no code implementations28 Nov 2019 Yixiang Wang, Feng Wu

To tackle this, we propose to train multiple policies for each agent and postpone the selection of the best policy at execution time.
