Cross-domain Cross-architecture Black-box Attacks on Fine-tuned Models with Transferred Evolutionary Strategies

1 code implementation28 Aug 2022 Yinghua Zhang, Yangqiu Song, Kun Bai, Qiang Yang

To successfully attack fine-tuned models under both settings, we propose to first train an adversarial generator against the source model, which adopts an encoder-decoder architecture and maps a clean input to an adversarial example.

Two Sides of the Same Coin: White-box and Black-box Attacks for Transfer Learning

1 code implementation25 Aug 2020 Yinghua Zhang, Yangqiu Song, Jian Liang, Kun Bai, Qiang Yang

To systematically measure the effect of both white-box and black-box attacks, we propose a new metric to evaluate how transferable are the adversarial examples produced by a source model to a target model.

Fisher Deep Domain Adaptation

1 code implementation12 Mar 2020 Yinghua Zhang, Yu Zhang, Ying WEI, Kun Bai, Yangqiu Song, Qiang Yang

Though the learned representations are separable in the source domain, they usually have a large variance and samples with different class labels tend to overlap in the target domain, which yields suboptimal adaptation performance.

Domain Adaptation

Parameter Transfer Unit for Deep Neural Networks

no code implementations23 Apr 2018 Yinghua Zhang, Yu Zhang, Qiang Yang

Unfortunately, the transferability is usually defined as discrete states and it differs with domains and network architectures.
