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…
The Second Gap for Minimal Hypersurfaces in the Unit Sphere with Constant Cubic Trace
Shanlin Guan
Let , , be a closed oriented minimal hypersurface in the unit sphere with constant scalar curvature and constant $f_3=\tr(h^3)$, where is the second fundamental for…
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…
