PA-GMAE: A Position-Assigned Graph Masked Autoencoder for Point Cloud Representation Learning

Haifeng Yang, Lupeng Fang, Jianghui Cai, Jie Wang, Guojiao An, Lihua Hu

IJCAI 2026

Masked autoencoder have demonstrated excellent performance in point cloud representation learning and received widespread attention. However, due to the unstructured nature of point clouds, existing methods struggle to effectively model both local geometric information and global topological feature

Dynamic against Dynamic: An Open-Set Self-Learning Framework

Haifeng Yang, Chuanxing Geng, Pong C. Yuen, Songcan Chen

IJCAI 2024poster

In open set recognition, existing methods generally learn statically fixed decision boundaries to reject unknown classes. Though they have achieved promising results, such decision boundaries are evidently insufficient for universal unknown classes in dynamic and open scenarios as they can potential…
