Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.



Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Its about a certain form of reinforced learning, called Temporal Difference Learning:

https://inria.hal.science/hal-00840470/document at page 11.

The calculation is called simple because it follows directly from the definitions above. Simple means more like "follows directly from definition without fancy math tricks", not " everyone who can read could solve this in 10 minutes".

I think this is also mostly math related, not physics?

I had a good laugh anyway. Good meme

We've got the time dependent polar Schrödinger equation any time we want to pull out a ridiculous looking equation in pre-graduate level physics.

Reinforcement learning is a machine learning (ML) technique (“AI” in layman terms) for optimizing neural networks and other types of non-linear models.

As far as ML math goes, this is fairly tame. It looks complicated, but is spelled out clearly in the paper. A lot of these kind of theoretical papers — things that would get published in Automatica — are going to lean very heavy on math.
