Equivariant Flow Matching for Point Cloud Assembly
Ziming Wang, Nan Xue, Rebecka Jörnsten
The goal of point cloud assembly is to reconstruct a complete 3D shape by aligning multiple point cloud pieces. This work presents a novel equivariant solver for assembly tasks bas…

Theoretical Performance Guarantees for Partial Domain Adaptation via Partial Optimal Transport
Jayadev Naram, Fredrik Hellström, Ziming Wang +2
In many scenarios of practical interest, labeled data from a target distribution are scarce while labeled data from a related source distribution are abundant. One particular setti…

SE(3)-bi-equivariant Transformers for Point Cloud Assembly
Ziming Wang, Rebecka Jörnsten
Given a pair of point clouds, the goal of assembly is to recover a rigid transformation that aligns one point cloud to the other. This task is challenging because the point clouds…
