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…
RPMem: Learning Long-Term Recurrent Parametric Memory Across Sessions for LLM Agents
Fanyu Zhao, Ruike Cao, Liang Dong +6
Long-running LLM agents require memory that persists and evolves across sessions. Text-based memory retrieves and reconstructs past interactions at every query, making long-horizon…
Learning Hierarchical Orthogonal Prototypes for Generalized Few-Shot 3D Point Cloud Segmentation
Yifei Zhao, Fanyu Zhao, Zhongyuan Zhang +3
Generalized few-shot 3D point cloud segmentation aims to adapt to novel classes from only a few annotations while maintaining strong performance on base classes, but this remains c…
Uncertainty-aware Prototype Learning with Variational Inference for Few-shot Point Cloud Segmentation
Yifei Zhao, Fanyu Zhao, Yinsheng Li
Few-shot 3D semantic segmentation aims to generate accurate semantic masks for query point clouds with only a few annotated support examples. Existing prototype-based methods typic…
