Fast, Expressive SE Equivariant Networks through Weight-Sharing in Position-Orientation Space

Erik J Bekkers, Sharvaree Vadgama, Rob D Hesselink +2

Based on the theory of homogeneous spaces we derive geometrically optimal edge attributes to be used within the flexible message-passing framework. We formalize the notion of weigh…

On genuine invariance learning without weight-tying

Artem Moskalev, Anna Sepliarskaia, Erik J. Bekkers +1

In this paper, we investigate properties and limitations of invariance learned by neural networks from the data compared to the genuine invariance achieved through invariant weight…

Learned Gridification for Efficient Point Cloud Processing

Putri A. van der Linden, David W. Romero, Erik J. Bekkers

Neural operations that rely on neighborhood information are much more expensive when deployed on point clouds than on grid data due to the irregular distances between points in a p…

Regular SE(3) Group Convolutions for Volumetric Medical Image Analysis

Thijs P. Kuipers, Erik J. Bekkers

Regular group convolutional neural networks (G-CNNs) have been shown to increase model performance and improve equivariance to different geometrical symmetries. This work addresses…
