Why HN recommends it

Introduction to reinforcement learning by two founders of the field, free online. Covers foundations from multi-armed bandits to temporal difference learning, with a notation table; suits ML students and engineers.

Summarised by Claude from recommending comments

Reinforcement learning is the learning of a mapping from situations to actions so as to maximize a scalar reward or reinforcement signal. The learner is not told which action to take, as in most forms of machine learning, but instead must discover which actions yield the highest reward by trying them. In the most interesting and challenging cases, actions may affect not only the immediate reward, but also the next situation, and through that all subsequent rewards. These two characteristics -- trial-and-error search and delayed reward -- are the most important distinguishing features of reinfo

    Not sure if the authors will read this or not but I beg of you, please put a table of notation in the forward. The Sutton and Barto Reinforcement Learning book did that for basically every notation that wasn't basic algebra and it's been extremely helpful. Just labeling things I had never seen before, like indicator functions, was extremely valuable. Especially…

    Like others have said, this seems to be a generalization of the problem of reinforcement learning. For a good introduction to the subject, check out Reinforcement Learning by Sutton & Barto [1]. After reading the first few chapters, you'll be able to understand most of that equation. [1] http://webdocs.cs.ualberta.ca/~sutton/book/the-book.html

I'm very interested to see what a book focused more narrowly on RL will be like-- Sutton's Introduction to Reinforcement Learning[0] is fantastic, but if you're going to do research on RL, another text such as this one is necessary. 0. http://www.incompleteideas.net/book/the-book-2nd.html
