Adversarial Paraphrasing: A Universal Attack for Humanizing AI-Generated Text

NeurIPS 2025poster

The increasing capabilities of Large Language Models (LLMs) have raised concerns about their misuse in AI-generated plagiarism and social engineering. While various AI-generated text detectors have been proposed to mitigate these risks, many remain vulnerable to simple evasion techniques such as par…

Fast Adversarial Attacks on Language Models In One GPU Minute

ICML 2024poster

In this paper, we introduce a novel class of fast, beam search-based adversarial attack (BEAST) for Language Models (LMs). BEAST employs interpretable parameters, enabling attackers to balance between attack speed, success rate, and the readability of adversarial prompts. The computational efficienc…

LLM-Check: Investigating Detection of Hallucinations in Large Language Models

NeurIPS 2024poster

While Large Language Models (LLMs) have become immensely popular due to their outstanding performance on a broad range of tasks, these models are prone to producing hallucinations— outputs that are fallacious or fabricated yet often appear plausible or tenable at a glance. In this paper, we conduct…

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

ICLR 2024poster

In light of recent advancements in generative AI models, it has become essential to distinguish genuine content from AI-generated one to prevent the malicious usage of fake materials as authentic ones and vice versa. Various techniques have been introduced for identifying AI-generated images, with w…

Exploring Geometry of Blind Spots in Vision models

NeurIPS 2023spotlight

Despite the remarkable success of deep neural networks in a myriad of settings, several works have demonstrated their overwhelming sensitivity to near-imperceptible perturbations, known as adversarial attacks. On the other hand, prior works have also observed that deep networks can be under-sensitiv…

Shallow RNN: Accurate Time-series Classification on Resource Constrained Devices

NeurIPS 2019poster

Recurrent Neural Networks (RNNs) capture long dependencies and context, and 2 hence are the key component of typical sequential data based tasks. However, the sequential nature of RNNs dictates a large inference cost for long sequences even if the hardware supports parallelization. To induce long-te…
