Backdoor Attacks and Defenses in Federated Learning: Survey, Challenges and Future Research Directions

no code implementations3 Mar 2023 Thuy Dung Nguyen, Tuan Nguyen, Phi Le Nguyen, Hieu H. Pham, Khoa Doan, Kok-Seng Wong

Federated learning (FL) is a machine learning (ML) approach that allows the use of distributed data without compromising personal privacy.

Asymmetric Hashing for Fast Ranking via Neural Network Measures

no code implementations1 Nov 2022 Khoa Doan, Shulong Tan, Weijie Zhao, Ping Li

Previous learning-to-hash approaches are also not suitable to solve the fast item ranking problem since they can take a significant amount of time and computation to train the hash functions.

Backdoor Attack with Imperceptible Input and Latent Modification

no code implementations NeurIPS 2021 Khoa Doan, Yingjie Lao, Ping Li

Many existing countermeasures found that backdoor tends to leave tangible footprints in the latent or feature space, which can be utilized to mitigate backdoor attacks. In this paper, we extend the concept of imperceptible backdoor from the input space to the latent representation, which significantly improves the effectiveness against the existing defense mechanisms, especially those relying on the distinguishability between clean inputs and backdoor inputs in latent space.

LIRA: Learnable, Imperceptible and Robust Backdoor Attacks

2 code implementations ICCV 2021 Khoa Doan, Yingjie Lao, Weijie Zhao, Ping Li

Under this optimization framework, the trigger generator function will learn to manipulate the input with imperceptible noise to preserve the model performance on the clean data and maximize the attack success rate on the poisoned data.

Regression via Implicit Models and Optimal Transport Cost Minimization

1 code implementation3 Mar 2020 Saurav Manchanda, Khoa Doan, Pranjul Yadav, S. Sathiya Keerthi

This paper addresses the classic problem of regression, which involves the inductive learning of a map, $y=f(x, z)$, $z$ denoting noise, $f:\mathbb{R}^n\times \mathbb{R}^k \rightarrow \mathbb{R}^m$.
