Geometric Deep Learning is an attempt for geometric unification of a broad class of ML problems from the perspectives of symmetry and invariance. These principles not only underlie the breakthrough performance of convolutional neural networks and the recent success of graph neural networks but also provide a principled way to construct new types of problem-specific inductive biases. — This blog post was co-authored with Joan Bruna, Taco Cohen, and Petar Veličković and is based on the new “proto-book” M. M. Bronstein, J. Bruna, T. Cohen, and P. Veličković, Geometric Deep Learning: Grids, Groups, Graphs, Geodesics, and Gauges (2021), Petar’s talk at Cambridge and Michael’s keynote talk at ICLR…
