Securely Fine-tuning Pre-trained Encoders Against Adversarial Examples

1 code implementation16 Mar 2024 Ziqi Zhou, Minghui Li, Wei Liu, Shengshan Hu, Yechao Zhang, Wei Wan, Lulu Xue, Leo Yu Zhang, Dezhong Yao, Hai Jin

In response to these challenges, we propose Genetic Evolution-Nurtured Adversarial Fine-tuning (Gen-AF), a two-stage adversarial fine-tuning approach aimed at enhancing the robustness of downstream models.

Why Does Little Robustness Help? Understanding and Improving Adversarial Transferability from Surrogate Training

1 code implementation15 Jul 2023 Yechao Zhang, Shengshan Hu, Leo Yu Zhang, Junyu Shi, Minghui Li, Xiaogeng Liu, Wei Wan, Hai Jin

Building on these insights, we explore the impacts of data augmentation and gradient regularization on transferability and identify that the trade-off generally exists in the various training mechanisms, thus building a comprehensive blueprint for the regulation mechanism behind transferability.

A scalable deep learning approach for solving high-dimensional dynamic optimal transport

no code implementations16 May 2022 Wei Wan, Yuejin Zhang, Chenglong Bao, Bin Dong, Zuoqiang Shi

In this work, we propose a deep learning based method to solve the dynamic optimal transport in high dimensional space.

Challenges and Approaches for Mitigating Byzantine Attacks in Federated Learning

no code implementations29 Dec 2021 Junyu Shi, Wei Wan, Shengshan Hu, Jianrong Lu, Leo Yu Zhang

Then we propose a new byzantine attack method called weight attack to defeat those defense schemes, and conduct experiments to demonstrate its threat.

Nonlocal Patches based Gaussian Mixture Model for Image Inpainting

no code implementations22 Sep 2019 Wei Wan, Jun Liu

By a maximum a posteriori (MAP) estimation, we formulate a new regularization term according to the log-likelihood function of the mixture model.
