Momentum Adversarial Distillation: Handling Large Distribution Shifts in Data-Free Knowledge Distillation

no code implementations21 Sep 2022 Kien Do, Hung Le, Dung Nguyen, Dang Nguyen, Haripriya Harikumar, Truyen Tran, Santu Rana, Svetha Venkatesh

Since the EMA generator can be considered as an ensemble of the generator's old versions and often undergoes a smaller change in updates compared to the generator, training on its synthetic samples can help the student recall the past knowledge and prevent the student from adapting too quickly to new updates of the generator.

Defense Against Multi-target Trojan Attacks

no code implementations8 Jul 2022 Haripriya Harikumar, Santu Rana, Kien Do, Sunil Gupta, Wei Zong, Willy Susilo, Svetha Venkastesh

To defend against this attack, we first introduce a trigger reverse-engineering mechanism that uses multiple images to recover a variety of potential triggers.

Semantic Host-free Trojan Attack

no code implementations26 Oct 2021 Haripriya Harikumar, Kien Do, Santu Rana, Sunil Gupta, Svetha Venkatesh

In this paper, we propose a novel host-free Trojan attack with triggers that are fixed in the semantic space but not necessarily in the pixel space.

Scalable Backdoor Detection in Neural Networks

no code implementations10 Jun 2020 Haripriya Harikumar, Vuong Le, Santu Rana, Sourangshu Bhattacharya, Sunil Gupta, Svetha Venkatesh

Recently, it has been shown that deep learning models are vulnerable to Trojan attacks, where an attacker can install a backdoor during training time to make the resultant model misidentify samples contaminated with a small trigger patch.
