Uncertainty Gates the Gradient: Adaptive Updates for Generalized Few-Shot 3D Segmentation
Yifei Zhao, Fanyu Zhao, Shengtang Wu +3
In generalized few-shot 3D point cloud segmentation, support annotations are often compromised by sparsity and occlusion. Blindly adapting to such low quality samples risks learnin…

Do 3D Large Language Models Really Use 3D Evidence?
Yifei Zhao, Fanyu Zhao, Han Zhang +6
Recent 3D Large Language Models (3D-LLMs) have shown strong performance on scene question answering with extensive post-training. Yet, existing benchmarks rarely evaluate how 3D-LL…
