Reply to comment by fuscarili in [D] I'm at a crossroads: Bayesian methods VS Reinforcement Learning, which to choose? by fuscarili

You can find good lectures on all of these topics on youtube, coursera, etc, but that's also true about Bayesian methods. RL is more fun IMO, but less employable for now. RL is used all over the place for things like recommender engines, ad promotion, etc. The concepts are super valuable. Bayesian methods are a bit more generic and common, and tbh are going out of vogue in most of robotics.

Interesting! And do you know btw if RL is a useful tool in finance? I have heard really polarized opinions about its effectiveness for algorithmic trading/trading bots. Some say it's awful and other people that it's the most promising technology for it.

There are smarter people than me out there, so maybe I’m missing something, but the market doesn’t change trajectories because of any move you make. All finance wants to do is guess what the movement will be (up, down, how much). This is a classification or regression problem, not RL.
