Optimization and Optimizers for Adversarial Robustness

no code implementations23 Mar 2023 Hengyue Liang, Buyun Liang, Le Peng, Ying Cui, Tim Mitchell, Ju Sun

Taking advantage of PWCF and other existing numerical algorithms, we further explore the distinct patterns in the solutions found for solving these optimization problems using various combinations of losses, perturbation models, and optimization algorithms.

Optimization for Robustness Evaluation beyond $\ell_p$ Metrics

no code implementations2 Oct 2022 Hengyue Liang, Buyun Liang, Ying Cui, Tim Mitchell, Ju Sun

Empirical evaluation of deep learning models against adversarial attacks entails solving nontrivial constrained optimization problems.

Early Stopping for Deep Image Prior

1 code implementation11 Dec 2021 Hengkang Wang, Taihui Li, Zhong Zhuang, Tiancong Chen, Hengyue Liang, Ju Sun

In this regard, the majority of DIP works for vision tasks only demonstrates the potential of the models -- reporting the peak performance against the ground truth, but provides no clue about how to operationally obtain near-peak performance without access to the groundtruth.

Self-Validation: Early Stopping for Single-Instance Deep Generative Priors

2 code implementations23 Oct 2021 Taihui Li, Zhong Zhuang, Hengyue Liang, Le Peng, Hengkang Wang, Ju Sun

Recent works have shown the surprising effectiveness of deep generative models in solving numerous image reconstruction (IR) tasks, even without training data.

A Deep Learning Approach to Grasping the Invisible

1 code implementation11 Sep 2019 Yang Yang, Hengyue Liang, Changhyun Choi

The target-oriented motion critic, which maps both visual observations and target information to the expected future rewards of pushing and grasping motion primitives, is learned via deep Q-learning.
