I am currently pursuing a Master of Science in Computer Engineering at the National University of Singapore (NUS). I obtained my undergraduate degree in Artificial Intelligence from the South China University of Technology (SCUT). I am also a research intern at the NUS LV Lab, supervised by Prof. Shuicheng Yan, and work closely with Dr. Xiaobin Hu.

Research Interests: Efficient AI, Diffusion Model, MLLM, World Model.

I am currently seeking Spring/Fall 2027 PhD opportunities and am always open to research collaborations. Please feel free to contact me!

SPOT-E: Test-Time Entropy Shaping with Visual Spotlights for Frozen VLMs

SPOT-E test-time visual spotlight framework

Bo Yin, Xiaobin Hu, Chengming Xu, Ruolin Shen, Mo Yang, Jiangning Zhang, Peng-Tao Jiang, Cheng Tan, Shuicheng Yan

We introduce SPOT-E, a plug-and-play test-time visual adaptation framework that keeps the VLM frozen while optimizing question-conditioned visual spotlights through entropy shaping, improving evidence utilization without model retraining.

FeRA: Frequency-Energy Constrained Routing for Effective Diffusion Adaptation Fine-Tuning

FeRA: Frequency-Energy Constrained Routing for Effective Diffusion Adaptation Fine-Tuning

Bo Yin, Xiaobin Hu, Xingyu Zhou, Peng-Tao Jiang, Yue Liao, Junwei Zhu, Jiangning Zhang, Ying Tai, Chengjie Wang, Shuicheng Yan

We present a novel fine-tuning approach for diffusion models, termed Frequency-Energy constrained Routing Adaptation (FeRA), which uses frequency-domain analysis to guide the fine-tuning process, enhancing both efficiency and effectiveness.

Refinement Provenance Inference: Detecting LLM-Refined Training Prompts from Model Behavior

repro

Bo Yin, Qi Li, Runpeng Yu, Xinchao Wang

We propose an instance-level auditing method that infers, from a model’s behavior, whether it was trained on an original prompt or an LLM-refined version of that prompt within a mixed training corpus.

Under Review

FrameMorrow: Future-guided Frame Selection with Prospective Tokens for Long-Horizon Video Generation

FrameMorrow prospective frame selection and training overview

Bo Yin, Xiaobin Hu, Jiaqi Zhao, Shuicheng Yan

FrameMorrow predicts compact prospective tokens to select historical frames according to future information needs, improving long-horizon video generation across diverse models.

Vision-Language-Action Safety: Threats, Challenges, Evaluations, and Mechanisms

Vision-Language-Action Safety landscape framework

Qi Li*, Bo Yin*, Weiqi Huang*, Ruhao Liu*, Bojun Zou, Runpeng Yu, Jingwen Ye, Weihao Yu, Xinchao Wang

* Equal contribution.

We survey VLA safety across threats, defenses, evaluation, and deployment, highlighting the unique risks introduced by embodied vision-language-action systems.

Under Review

On-Policy Self-Evolution via Failure Trajectories for Agentic Safety Alignment

FATE on-policy self-evolution framework

Bo Yin, Qi Li, Xinchao Wang

We introduce FATE, an on-policy self-evolving framework that converts verifier-scored failure trajectories into repair supervision and uses Pareto-Front Policy Optimization to improve trajectory-level safety while preserving utility.

Under Review

Don’t Forget the Nonlinearity: Unlocking Activation Functions in Efficient Fine-Tuning

Don't Forget the Nonlinearity

Bo Yin, Xingyi Yang, Xinchao Wang

We propose a novel and effective fine-tuning paradigm that introduces learnable activation functions to adapt large pre-trained models to downstream tasks while preserving their computational efficiency.
