Do We Still Need Rotation-Invariant Architectures? A Statistical Robustness Benchmark for Point Cloud Classification
Abdulla Nasir Chowdhury, Gulpi Qorik Oktagalu Pratamasunu, Kazuhiro Fukui
A substantial line of work builds rotation invariance directly into point cloud architectures. We benchmark 10 architectures (PointNet, PointNet++, DGCNN, RIConv, RIConv++, RISurCo…

Two-point residual step size gradient methods for linear systems
Xin Xu
Kaczmarz-type methods often converge slowly when the coefficient matrix is ill-conditioned. In particular, when the smallest singular value is small, every row of the coefficient m…
