These kinds of manifolds have no “global” symmetry for a neural network to make equivariant assumptions about: Every location on them is different. “This framework is a fairly definitive answer to this problem of deep learning on curved surfaces,” Welling said. At the same time, Taco Cohen and his colleagues in Amsterdam were beginning to approach the same problem from the opposite direction.

In the case of a cat photo, a trained CNN may use filters that detect low-level features in the raw input pixels, such as edges. Convolutional networks became one of the most successful methods in deep learning by exploiting a simple example of this principle called “translation equivariance.” A window filter that detects a certain feature in an image — say, vertical edges — will slide (or “translate”) over the plane of pixels and encode the locations of all such vertical edges; it then creates a “feature map” marking these locations and passes it up to the next layer in the network. The theory of gauge-equivariant CNNs is so generalized that it automatically incorporates the built-in assumptions of previous geometric deep learning approaches — like rotational equivariance and shifting filters on spheres. ∙ 0 Michael Bronstein, a computer scientist at Imperial College London, coined the term “geometric deep learning” in 2015 to describe nascent efforts to get off flatland and design neural networks that could learn patterns in nonplanar data. 2 di...
