Think Twice Before Assure: Confidence Estimation for Large Language Models through Reflection on Multiple Answers

no code implementations15 Mar 2024 Moxin Li, Wenjie Wang, Fuli Feng, Fengbin Zhu, Qifan Wang, Tat-Seng Chua

Confidence estimation aiming to evaluate output trustability is crucial for the application of large language models (LLM), especially the black-box ones.

Gotcha! Don't trick me with unanswerable questions! Self-aligning Large Language Models for Responding to Unknown Questions

no code implementations23 Feb 2024 Yang Deng, Yong Zhao, Moxin Li, See-Kiong Ng, Tat-Seng Chua

Despite the remarkable abilities of Large Language Models (LLMs) to answer questions, they often display a considerable level of overconfidence even when the question does not have a definitive answer.

TAT-LLM: A Specialized Language Model for Discrete Reasoning over Tabular and Textual Data

no code implementations24 Jan 2024 Fengbin Zhu, Ziyang Liu, Fuli Feng, Chao Wang, Moxin Li, Tat-Seng Chua

In this work, we address question answering (QA) over a hybrid of tabular and textual data that are very common content on the Web (e. g. SEC filings), where discrete reasoning capabilities are often required.

Robust Prompt Optimization for Large Language Models Against Distribution Shifts

no code implementations23 May 2023 Moxin Li, Wenjie Wang, Fuli Feng, Yixin Cao, Jizhi Zhang, Tat-Seng Chua

In this light, we propose a new problem of robust prompt optimization for LLMs against distribution shifts, which requires the prompt optimized over the labeled source group can simultaneously generalize to an unlabeled target group.
