Collaborative LLM Numerical Reasoning with Local Data Protection

no code implementations1 Apr 2025 Min Zhang, Yuzhe Lu, Yun Zhou, Panpan Xu, Lin Lee Cheong, Chang-Tien Lu, Haozhu Wang

Furthermore, our method improves accuracy by 16. 2% - 43. 6% while reducing data leakage by 2. 3% - 44. 6% compared to existing data protection approaches.

Enhancing Multi-hop Reasoning in Vision-Language Models via Self-Distillation with Multi-Prompt Ensembling

no code implementations3 Mar 2025 Guande Wu, Huan Song, Yawei Wang, Qiaojing Yan, Yijun Tian, Lin Lee Cheong, Panpan Xu

However, while language models can effectively leverage chain-of-thought prompting for zero or few-shot learning, similar prompting strategies are less effective for multi-modal LLMs due to modality gaps and task complexity.
