SIEVE: Overcoming Topological Obstruction in Equivariant Self-Supervised Learning
Jongann Lee, Sun Woo Park, Yun Young Choi
We identify a theoretical incompatibility between 3D point cloud masked autoencoding and SE(3)-equivariant networks. We prove that standard masking triggers a topological collapse,…

The PWLR Graph Representation: A Persistent Weisfeiler-Lehman scheme with Random Walks for Graph Classification
Sun Woo Park, Yun Young Choi, Dosang Joe +2
This paper presents the Persistent Weisfeiler-Lehman Random walk scheme (abbreviated as PWLR) for graph representations, a novel mathematical framework which produces a collection…
