https://en.wikipedia.org/wiki/Hopf_algebra https://en.wikipedia.org/wiki/Hopf_algebra Look at the diagram. Do you see the path going through the middle? And the paths at the top and bottom (they are generalized convolutions)? Well a Hopf algebra "learns" by updating it's internal state in order to enforce an invariance between the middle path and the top and bottom paths. Allow me to restate it, it's an algebra that "learns". Reading about Hopf algebras is tripper than dropping acid.
