To Augment or Not to Augment? Diagnosing Distributional Symmetry Breaking

Hannah Lawrence, Elyssa Hofgard, Vasco Portilheiro +3

Symmetry-aware methods for machine learning, such as data augmentation and equivariant architectures, encourage correct model behavior on all transformations (e.g. rotations or per…

Improving Equivariant Networks with Probabilistic Symmetry Breaking

Hannah Lawrence, Vasco Portilheiro, Yan Zhang +1

Equivariance encodes known symmetries into neural networks, often enhancing generalization. However, equivariant networks cannot break symmetries: the output of an equivariant netw…
