Theory

For the theory behind group convolutions, we recommend the original paper on group convolutions by Taco Cohen and Max Welling and the book, lectures and notebooks on the geometric deep learning by Michael Bronstein, Joan Bruna, Taco Cohen and Petar Veličković, found here.

For an explanation in my own words and a step by step implementation from scratch of an early version of GroCo, see this Colab notebook.
