VLA-Mark: A cross modal watermark for large vision-language alignment models

EMNLP 2025

Vision-language models demand watermarking solutions that protect intellectual property without compromising multimodal coherence. Existing text watermarking methods disrupt visual-textual alignment through biased token selection and static strategies, leaving semantic-critical concepts vulnerable.

Arithmetic Reasoning with LLM: Prolog Generation & Permutation

NAACL 2024short

Instructing large language models (LLMs) to solve elementary school math problems has shown great success using Chain of Thought (CoT). However, the CoT approach relies on an LLM to generate a sequence of arithmetic calculations which can be prone to cascaded calculation errors. We hypothesize that…

Robust Unstructured Knowledge Access in Conversational Dialogue with ASR Errors

ICASSP 2022accepted

Performance of spoken language understanding (SLU) can be degraded with automatic speech recognition (ASR) errors. We propose a novel approach to improve SLU robustness by randomly corrupting clean training text with an ASR error simulator, followed by self-correcting the errors and minimizing the t…
