Measuring and Mitigating Name Biases in Neural Machine Translation

no code implementations ACL 2022 Jun Wang, Benjamin Rubinstein, Trevor Cohn

In this paper we describe a new source of bias prevalent in NMT systems, relating to translations of sentences containing person names.

IMBERT: Making BERT Immune to Insertion-based Backdoor Attacks

1 code implementation25 May 2023 Xuanli He, Jun Wang, Benjamin Rubinstein, Trevor Cohn

Backdoor attacks are an insidious security threat against machine learning models.

Mitigating Backdoor Poisoning Attacks through the Lens of Spurious Correlation

1 code implementation19 May 2023 Xuanli He, Qiongkai Xu, Jun Wang, Benjamin Rubinstein, Trevor Cohn

Modern NLP models are often trained over large untrusted datasets, raising the potential for a malicious adversary to compromise model behaviour.

TRS: Transferability Reduced Ensemble via Encouraging Gradient Diversity and Model Smoothness

1 code implementation NeurIPS 2021 Zhuolin Yang, Linyi Li, Xiaojun Xu, Shiliang Zuo, Qian Chen, Benjamin Rubinstein, Pan Zhou, Ce Zhang, Bo Li

To answer these questions, in this work we first theoretically analyze and outline sufficient conditions for adversarial transferability between models; then propose a practical algorithm to reduce the transferability between base models within an ensemble to improve its robustness.

On the Differential Privacy of Bayesian Inference

no code implementations22 Dec 2015 Zuhe Zhang, Benjamin Rubinstein, Christos Dimitrakakis

We study how to communicate findings of Bayesian inference to third parties, while preserving the strong guarantee of differential privacy.

no code implementations5 Jun 2013 Christos Dimitrakakis, Blaine Nelson, and Zuhe Zhang, Aikaterini Mitrokotsa, Benjamin Rubinstein

All our general results hold for arbitrary database metrics, including those for the common definition of differential privacy.
