Equivariant Neural Tangent Kernels

no code implementations10 Jun 2024 Philipp Misof, Pan Kessel, Jan E. Gerken

Equivariant neural networks have in recent years become an important technique for guiding architecture selection for neural networks with many applications in domains ranging from medical image analysis to quantum chemistry.

Emergent Equivariance in Deep Ensembles

no code implementations5 Mar 2024 Jan E. Gerken, Pan Kessel

We show that deep ensembles become equivariant for all inputs and at all training times by simply using data augmentation.

Diffeomorphic Counterfactuals with Generative Models

1 code implementation10 Jun 2022 Ann-Kathrin Dombrowski, Jan E. Gerken, Klaus-Robert Müller, Pan Kessel

Counterfactuals can explain classification decisions of neural networks in a human interpretable way.

Equivariance versus Augmentation for Spherical Images

1 code implementation8 Feb 2022 Jan E. Gerken, Oscar Carlsson, Hampus Linander, Fredrik Ohlsson, Christoffer Petersson, Daniel Persson

We compare the performance of the group equivariant networks known as S2CNNs and standard non-equivariant CNNs trained with an increasing amount of data augmentation.

Geometric Deep Learning and Equivariant Neural Networks

no code implementations28 May 2021 Jan E. Gerken, Jimmy Aronsson, Oscar Carlsson, Hampus Linander, Fredrik Ohlsson, Christoffer Petersson, Daniel Persson

We also discuss group equivariant neural networks for homogeneous spaces $\mathcal{M}=G/K$, which are instead equivariant with respect to the global symmetry $G$ on $\mathcal{M}$.
