IDEAL-Bench: Indoor Dataset and Evaluation suite for Analyzing 3D Layout reasoning

Yuening Cai, Junwei Zhou, Youran Qu, Yu-Wing Tai

Spatial question answering is the dominant paradigm for evaluating spatial intelligence in Vision-Language Models (VLMs), but it leaves a complementary axis of spatial competence under-evaluated: holistic 3D layout inference, which predicts every visible object's pose and extent…

Beyond MoCap: Scaling Motion Tokenizers with Synthetic Human Motion for Generative Modeling

Yiwen Yan, Wanning He, Yu-Wing Tai

Human motion generation models are fundamentally constrained by the limited diversity of motion capture datasets, which predominantly contain common, repetitive actions and fail to cover the long tail of complex human movements, resulting in a restricted motion vocabulary in lear…
