Fast Adversarial Attacks on Language Models In One GPU Minute

no code implementations23 Feb 2024 Vinu Sankar Sadasivan, Shoumik Saha, Gaurang Sriramanan, Priyatham Kattakinda, Atoosa Chegini, Soheil Feizi

Through human evaluations, we find that our untargeted attack causes Vicuna-7B-v1. 5 to produce ~15% more incorrect outputs when compared to LM outputs in the absence of our attack.

Robustness of AI-Image Detectors: Fundamental Limits and Practical Attacks

1 code implementation29 Sep 2023 Mehrdad Saberi, Vinu Sankar Sadasivan, Keivan Rezaei, Aounon Kumar, Atoosa Chegini, Wenxiao Wang, Soheil Feizi

Moreover, we show that watermarking methods are vulnerable to spoofing attacks where the attacker aims to have real images identified as watermarked ones, damaging the reputation of the developers.

Provable Robustness for Streaming Models with a Sliding Window

no code implementations28 Mar 2023 Aounon Kumar, Vinu Sankar Sadasivan, Soheil Feizi

Robustness certificates based on the assumption of independent input samples are not directly applicable in such scenarios.

Can AI-Generated Text be Reliably Detected?

1 code implementation17 Mar 2023 Vinu Sankar Sadasivan, Aounon Kumar, Sriram Balasubramanian, Wenxiao Wang, Soheil Feizi

In particular, we develop a recursive paraphrasing attack to apply on AI text, which can break a whole range of detectors, including the ones using the watermarking schemes as well as neural network-based detectors, zero-shot classifiers, and retrieval-based detectors.

OSSuM: A Gradient-Free Approach For Pruning Neural Networks At Initialization

no code implementations29 Sep 2021 Vinu Sankar Sadasivan, Jayesh Malaviya, Anirban Dasgupta

Recent works attempt to prune neural networks at initialization to design sparse networks that can be trained efficiently.

Statistical Measures For Defining Curriculum Scoring Function

1 code implementation27 Feb 2021 Vinu Sankar Sadasivan, Anirban Dasgupta

Curriculum learning is a training strategy that sorts the training examples by some measure of their difficulty and gradually exposes them to the learner to improve the network performance.
