EAGLE: A Domain Generalization Framework for AI-generated Text Detection

no code implementations23 Mar 2024 Amrita Bhattacharjee, Raha Moraffah, Joshua Garland, Huan Liu

With the advancement in capabilities of Large Language Models (LLMs), one major step in the responsible and safe use of such LLMs is to be able to detect text generated by these models.

How Reliable Are AI-Generated-Text Detectors? An Assessment Framework Using Evasive Soft Prompts

no code implementations8 Oct 2023 Tharindu Kumarage, Paras Sheth, Raha Moraffah, Joshua Garland, Huan Liu

The novel universal evasive prompt is achieved in two steps: First, we create an evasive soft prompt tailored to a specific PLM through prompt tuning; and then, we leverage the transferability of soft prompts to transfer the learned evasive soft prompt from one PLM to another.

Towards LLM-guided Causal Explainability for Black-box Text Classifiers

no code implementations23 Sep 2023 Amrita Bhattacharjee, Raha Moraffah, Joshua Garland, Huan Liu

Inspired by recent endeavors to utilize Large Language Models (LLMs) as experts, in this work, we aim to leverage the instruction-following and textual understanding capabilities of recent state-of-the-art LLMs to facilitate causal explainability via counterfactual explanation generation for black-box text classifiers.

Stylometric Detection of AI-Generated Text in Twitter Timelines

1 code implementation7 Mar 2023 Tharindu Kumarage, Joshua Garland, Amrita Bhattacharjee, Kirill Trapeznikov, Scott Ruston, Huan Liu

However, tweets are inherently short, thus making it difficult for current state-of-the-art pre-trained language model-based detectors to accurately detect at what point the AI starts to generate tweets in a given Twitter timeline.
