Any-Subgroup Equivariant Networks via Symmetry Breaking

Abhinav Goel, Derek Lim, Hannah Lawrence +2

The inclusion of symmetries as an inductive bias, known as equivariance, often improves generalization on geometric data (e.g. grids, sets, and graphs). However, equivariant archit…

Quantitative Approximation Rates for Group Equivariant Learning

Jonathan W. Siegel, Snir Hordan, Hannah Lawrence +2

The universal approximation theorem establishes that neural networks can approximate any continuous function on a compact set. Later works in approximation theory provide quantitat…

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…

Equivariant Frames and the Impossibility of Continuous Canonicalization

Nadav Dym, Hannah Lawrence, Jonathan W. Siegel

Canonicalization provides an architecture-agnostic method for enforcing equivariance, with generalizations such as frame-averaging recently gaining prominence as a lightweight and…

On the hardness of learning under symmetries

Bobak T. Kiani, Thien Le, Hannah Lawrence +2

We study the problem of learning equivariant neural networks via gradient descent. The incorporation of known symmetries ("equivariance") into neural nets has empirically improved…

Learning Polynomial Problems with Equivariance

Hannah Lawrence, Mitchell Tong Harris

Optimizing and certifying the positivity of polynomials are fundamental primitives across mathematics and engineering applications, from dynamical systems to operations research. H…
