RAW: A Robust and Agile Plug-and-Play Watermark Framework for AI-Generated Images with Provable Guarantees

no code implementations23 Jan 2024 Xun Xian, Ganghua Wang, Xuan Bi, Jayanth Srinivasa, Ashish Kundu, Mingyi Hong, Jie Ding

Subsequently, we employ a classifier that is jointly trained with the watermark to detect the presence of the watermark.

Demystifying Poisoning Backdoor Attacks from a Statistical Perspective

Mitigating Group Bias in Federated Learning: Beyond Local Fairness

no code implementations17 May 2023 Ganghua Wang, Ali Payani, Myungjin Lee, Ramana Kompella

While many mitigation strategies have been proposed in centralized learning, many of these methods are not directly applicable in federated learning, where data is privately stored on multiple clients.

Pruning Deep Neural Networks from a Sparsity Perspective

2 code implementations ICLR 2023 Enmao Diao, Ganghua Wang, Jiawei Zhan, Yuhong Yang, Jie Ding, Vahid Tarokh

Our extensive experiments corroborate the hypothesis that for a generic pruning procedure, PQI decreases first when a large model is being effectively regularized and then increases when its compressibility reaches a limit that appears to correspond to the beginning of underfitting.
