Perils of Self-Feedback: Self-Bias Amplifies in Large Language Models

no code implementations18 Feb 2024 Wenda Xu, Guanglei Zhu, Xuandong Zhao, Liangming Pan, Lei LI, William Yang Wang

Recent studies show that self-feedback improves large language models (LLMs) on certain tasks while worsens other tasks.

INSTRUCTSCORE: Explainable Text Generation Evaluation with Finegrained Feedback

1 code implementation23 May 2023 Wenda Xu, Danqing Wang, Liangming Pan, Zhenqiao Song, Markus Freitag, William Yang Wang, Lei LI

By harnessing both explicit human instruction and the implicit knowledge of GPT-4, we fine-tune a text evaluation metric based on LLaMA, producing both a score for generated text and a human readable diagnostic report.

Anticipating the Unseen Discrepancy for Vision and Language Navigation

no code implementations10 Sep 2022 Yujie Lu, Huiliang Zhang, Ping Nie, Weixi Feng, Wenda Xu, Xin Eric Wang, William Yang Wang

In this paper, we propose an Unseen Discrepancy Anticipating Vision and Language Navigation (DAVIS) that learns to generalize to unseen environments via encouraging test-time visual consistency.
