Equivariance to symmetry transformations is one of the first rational principles for neural network architecture design. Equivariant networks have shown excellent performance on vision and medical imaging problems that exhibit symmetries. In this talk, I will show how this principle can be extended to data defined on general manifolds, using ideas from theoretical physics. We use the new theory to develop a highly practical and scalable alternative to Spherical CNNs, and show that this method outperforms previous methods on global climate pattern segmentation and omnidirectional vision.
