Baiqiao Yin

Baiqiao Yin「尹柏乔」

Hi! I'm Baiqiao Yin. I am an incoming PhD student at Nanyang Technological University (NTU), advised by Ziwei Liu.
Previously, I was a visiting student at New York University, advised by Saining Xie. I received my B.Eng. in Intelligent Science and Technology from SYSU, where I worked closely with Xiaodan Liang.
I was also fortunate to collaborate with Fei-Fei Li, Jiajun Wu, Manling Li, and Yiming Li.
If you think there is anything interesting we can discuss, feel free to email me!

📝Research

💬My research interests lie in spatial intelligence. Currently, my focus is on designing spatial intelligence agents with the following capabilities:

Spatial Representation
Closed-loop Spatial Intelligence
Physical Intelligence
Spatial Consistency Perception

	MindBlock: Probing Spatial Assembly and Structure in Unified Multimodal Models Baiqiao Yin, Junhao Liu, Han Yin, Heyang Yu, Tingxuan Zhang, Zhiheng Li, Chengzu Li, Jihan Yang, Manling Li, Chen Feng, Yiming Li ECCV*, 2026 paper / dataset / code Key Takeaway: True spatial intelligence requires active construction, not just 2D QA. Current unified multimodal models show a perception–execution gap: they often recognize the intended next state yet fail to generate it, and 2D similarity can conceal incoherent 3D geometry.
	Spatial Mental Modeling from Limited Views Baiqiao Yin, Qineng Wang, Pingyue Zhang, Jianshu Zhang, Kangrui Wang, Zihan Wang, Jieyu Zhang, Keshigeyan Chandrasegaran, Han Liu, Ranjay Krishna, Saining Xie, Manling Li, Jiajun Wu, Li Fei-Fei (Best Paper)ICCV Workshop on Structural Priors for Vision (SP4V)/ (Oral)ACMMM Workshop on Multimodal Foundation Models for Spatial Intelligence (MFMSI), 2025 project page / arXiv Key Takeaway: Guiding VLMs to first generate cognitive maps, then reason upon them, is an effective approach to approximate spatial mental modeling with limited views.
	⭐Awesome Spatial Intelligence in VLM (500+ Stars) Baiqiao Yin GitHub Repository, 2024-Present GitHub A curated collection of papers, datasets, and resources on spatial intelligence in vision-language models, maintained and regularly updated with the latest research developments.
	Skeleton2Point: Recognizing Skeleton-Based Actions as Point Clouds Baiqiao Yin, Jiaying Lin, Jiajun Wen, Yue Li, Jinfu Liu, Yanfei Wang, Mengyuan Liu IROS, 2025(Oral) project page / paper Regard skeleton joints as point cloud via incorporating the position information of skeletons into point cloud methods, demonstrating the validity of modeling position relationships with 3D coordinates.
	TheaterGen: Character Management with LLM for Consistent Multi-turn Image Generation Junhao Cheng, Baiqiao Yin, Kaixin Cai, Minbin Huang, Hanhui Li, Yuxin He, Xi Lu, Yue Li, Yifei Li, Yiqiang Yan, Xiaodan Liang CVPR Workshop, 2026 project page / paper / arxiv Theatergen can interact with users to consistently generate images over multiple Turns.
	HDBN: A Novel Hybrid Dual-branch Network for Robust Skeleton-based Action Recognition Jinfu Liu, Baiqiao Yin, Jiaying Lin, Jiajun Wen, Yue Li, Mengyuan Liu ICME, 2024 code / paper Benefits from the graph convolutional network's proficiency in handling graph-structured data and the powerful modeling capabilities of Transformers for global information.
	LVLM-CL: Make Large Vision-Language Models Work Better Under Continual Learning Settings Baiqiao Yin, Tech Report paper Devise a task-specific continual learning setting especially for LVLMs by classifying the instruction tuning data for the second finetune process of LVLMs into several different tasks
