Benchmarking Adversarial Robustness of Compressed Deep Learning Models

no code implementations16 Aug 2023 Brijesh Vora, Kartik Patwari, Syed Mahbub Hafiz, Zubair Shafiq, Chen-Nee Chuah

Our findings reveal that while the benefits of pruning enhanced generalizability, compression, and faster inference times are preserved, adversarial robustness remains comparable to the base model.

PURL: Safe and Effective Sanitization of Link Decoration

1 code implementation7 Aug 2023 Shaoor Munir, Patrick Lee, Umar Iqbal, Zubair Shafiq, Sandra Siby

While privacy-focused browsers have taken steps to block third-party cookies and mitigate browser fingerprinting, novel tracking techniques that can bypass existing countermeasures continue to emerge.

A Girl Has A Name, And It's ... Adversarial Authorship Attribution for Deobfuscation

1 code implementation22 Mar 2022 Wanyue Zhai, Jonathan Rusert, Zubair Shafiq, Padmini Srinivasan

Specifically, they are not evaluated against adversarially trained authorship attributors that are aware of potential obfuscation.

On The Robustness of Offensive Language Classifiers

1 code implementation ACL 2022 Jonathan Rusert, Zubair Shafiq, Padmini Srinivasan

Social media platforms are deploying machine learning based offensive language classification systems to combat hateful, racist, and other forms of offensive speech at scale.

AutoFR: Automated Filter Rule Generation for Adblocking

1 code implementation25 Feb 2022 Hieu Le, Salma Elmalaki, Athina Markopoulou, Zubair Shafiq

AutoFR is effective: it generates filter rules that can block 86% of the ads, as compared to 87% by EasyList, while achieving comparable visual breakage.

Avengers Ensemble! Improving Transferability of Authorship Obfuscation

no code implementations15 Sep 2021 Muhammad Haroon, Fareed Zaffar, Padmini Srinivasan, Zubair Shafiq

Our experiments show that if an obfuscator can evade an ensemble attribution classifier, which is based on multiple base attribution classifiers, it is more likely to transfer to different attribution classifiers.

Fingerprinting Fine-tuned Language Models in the Wild

1 code implementation Findings (ACL) 2021 Nirav Diwan, Tanmoy Chakravorty, Zubair Shafiq

Prior work on fingerprinting LMs is limited to attributing synthetic text generated by a handful (usually < 10) of pre-trained LMs.

Through the Looking Glass: Learning to Attribute Synthetic Text Generated by Language Models

no code implementations EACL 2021 Shaoor Munir, Brishna Batool, Zubair Shafiq, Padmini Srinivasan, Fareed Zaffar

Given the potential misuse of recent advances in synthetic text generation by language models (LMs), it is important to have the capacity to attribute authorship of synthetic text.

AdGraph: A Graph-Based Approach to Ad and Tracker Blocking

1 code implementation22 May 2018 Umar Iqbal, Peter Snyder, Shitong Zhu, Benjamin Livshits, Zhiyun Qian, Zubair Shafiq

AdGraph differs from existing approaches by building a graph representation of the HTML structure, network requests, and JavaScript behavior of a webpage, and using this unique representation to train a classifier for identifying advertising and tracking resources.
