Understanding the REINFORCE Estimator from Scratch
fpedregosa · x · 2026-07-13
This post shares and quotes a new blog series aimed at understanding modern reinforcement learning algorithms from the ground up.
The first part covers the classic REINFORCE estimator:
- How to derive an unbiased policy gradient without differentiating through the environment
- And the variance analysis of this estimator
The reposter mentioned that the author's blog is "more helpful than many books."
