Permutation-equivariant neural network
WebIn this work, we construct a neural architecture that is capable of perfectly recovering the optimal symmetric mech- anism. We further demonstrate that permutation-equivariant architectures are not only capable of recovering previous re- sults, they also have better generalization properties. 1 Introduction WebDec 5, 2024 · Implemented following this paper: Permutation-equivariant neural networks applied to dynamics prediction.

Permutation-equivariance and proximity-awareness are two important properties … WebSep 5, 2024 · Graph neural networks (GNNs) are emerging machine learning models on graphs. One key property behind the expressiveness of existing GNNs is that the learned node representations are permutation-equivariant. Though being a desirable property for certain tasks, however, permutation-equivariance prevents GNNs from being proximity …

It is also equivariant to permutations of the input point labels. We show that the SE(3)-Transformer resolves an issue with concurrent SE(3)-equivariant neural networks, which suffer from angularly constrained filters. We introduce a Pytorch implementation of spherical harmonics, which is 10x faster than

On top of this we required invariance with respect to the spatial transformations of translations, rotations and reflections. This gives us what is called an E(3)-equivariant GNN (E(3) is the name for these transformations in 3-dimensional space).
