In this letter we show how the computation of tensor products and branching rules of irreducible representations is machine-learnable, and can achieve relative speed-ups of orders of magnitude in comparison to the non-ML algorithms. ? 2021 The Author(s)journal article10.1016/j.physletb.2021.1362972-s2.0-85104651780
