PMark: Towards Robust and Distortion-free Semantic-level Watermarking with Channel Constraints

ICLR 2026poster

Semantic-level watermarking (SWM) for large language models (LLMs) enhances watermarking robustness against text modifications and paraphrasing attacks by treating the sentence as the fundamental unit. However, existing methods still lack strong theoretical guarantees of robustness, and reject-sampl…

Do BERT-Like Bidirectional Models Still Perform Better on Text Classification in the Era of LLMs?

EMNLP 2025

The rapid adoption of LLMs has overshadowed the potential advantages of traditional BERT-like models in text classification. This study challenges the prevailing “LLM-centric” trend by systematically comparing three category methods, *i.e.,* BERT-like models fine-tuning, LLM internal state utilizati

PhysicsArena: The First Multimodal Physics Reasoning Benchmark Exploring Variable, Process, and Solution Dimensions

EMNLP 2025

Multimodal Large Language Models (MLLMs) have demonstrated remarkable capabilities in diverse reasoning tasks, yet their application to complex physics reasoning remains underexplored. Physics reasoning presents unique challenges, requiring grounding in physical conditions and the interpretation of

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.

Automated Non-Invasive Measurement of Sperm Motility and Morphology Parameters

ICRA 2018poster

Measuring the motility and morphology parameters of motile cells is important for revealing their functional characteristics. This paper presents automation techniques that, for the first time, enable automated, non-invasive measurement of motility and morphology parameters of individual sperms. Com…
