SMART-PC: Skeletal Model Adaptation for Robust Test-Time Training in Point Clouds
Skeleton-based pretraining plus BatchNorm-only test-time adaptation gives fast, accurate 3D point cloud classification under corruption on ModelNet40-C and ScanObjectNN-C, but not uniformly across all tested benchmarks.
