Advancing the Robustness of Large Language Models through Self-Denoised Smoothing

1 code implementation18 Apr 2024 Jiabao Ji, Bairu Hou, Zhen Zhang, Guanhua Zhang, Wenqi Fan, Qing Li, Yang Zhang, Gaowen Liu, Sijia Liu, Shiyu Chang

Although large language models (LLMs) have achieved significant success, their vulnerability to adversarial perturbations, including recent jailbreak attacks, has raised considerable concerns.

Defending Large Language Models against Jailbreak Attacks via Semantic Smoothing

1 code implementation25 Feb 2024 Jiabao Ji, Bairu Hou, Alexander Robey, George J. Pappas, Hamed Hassani, Yang Zhang, Eric Wong, Shiyu Chang

Aligned large language models (LLMs) are vulnerable to jailbreaking attacks, which bypass the safeguards of targeted LLMs and fool them into generating objectionable content.

Towards Coherent Image Inpainting Using Denoising Diffusion Implicit Models

1 code implementation6 Apr 2023 Guanhua Zhang, Jiabao Ji, Yang Zhang, Mo Yu, Tommi Jaakkola, Shiyu Chang

COPAINT also uses the Bayesian framework to jointly modify both revealed and unrevealed regions, but approximates the posterior distribution in a way that allows the errors to gradually drop to zero throughout the denoising steps, thus strongly penalizing any mismatches with the reference image.

Controlling the Focus of Pretrained Language Generation Models

1 code implementation Findings (ACL) 2022 Jiabao Ji, Yoon Kim, James Glass, Tianxing He

This work aims to develop a control mechanism by which a user can select spans of context as "highlights" for the model to focus on, and generate relevant output.
