Bounds of Chain-of-Thought Robustness: Reasoning Steps, Embed Norms, and Beyond

ICLR 2026poster

Existing research indicates that the output of **Chain-of-Thought (CoT)** is significantly affected by input perturbations. Although many methods aim to mitigate such impact by optimizing prompts, a theoretical explanation of how these perturbations influence CoT outputs remains an open area of re…

MULTITAT: Benchmarking Multilingual Table-and-Text Question Answering

EMNLP 2025

Question answering on the hybrid context of tables and text (TATQA) is a critical task, with broad applications in data-intensive domains. However, existing TATQA datasets are limited to English, leading to several drawbacks: (i) They overlook the challenges of multilingual TAT-QA and cannot assess

SCITAT: A Question Answering Benchmark for Scientific Tables and Text Covering Diverse Reasoning Types

ACL 2025finding

Scientific question answering (SQA) is an important task aimed at answering questions based on papers. However, current SQA datasets have limited reasoning types and neglect the relevance between tables and text, creating a significant gap with real scenarios. To address these challenges, we propose…
