I'm strongly convinced that the brain works like a Hopf algebra.

https://en.wikipedia.org/wiki/Hopf_algebra

It works by enforcing an invariant between the middle path (epsilon -> eta, corresponds to current understanding) and the top/bottom paths.

The coalgebra (the delta symbol in the diagram) generates possible candidates (predictive coding) that are then passed through rest of the path and collapsed and combined in accordance with observed phenomena.

The algebra updates the middle path and the top/bottom paths in order to unify current understanding with observed phenomena.

The middle path corresponds to the feedback in an electric circuit with feedback.

It's the part that prevents the system from wild oscillations.

That is inscrutably abstract and jargony.

Spend a little bit of time on it, it's a lot more understandable than you think.

Peep this paper https://arxiv.org/abs/1206.3620.

Feynman would say... Oh well, nevermind.

You have been shamelessly self-promoting your Hopf algebra/deep learning research on a very large percentage of posts I have seen on HN lately, to the degree that I actually felt the need to log in so as to be able to comment on it. Please. Stop.

People need to know. Also I'm not promoting my research in this port, I'm promoting Hopf algebra.
