Learning RL From Scratch: Dev Publishes One-Page Basics Notes on neatrl.com
East-Muffin-6472 · reddit · 2026-10-26
A Reddit user is documenting their journey of learning reinforcement learning from scratch, releasing a series of short notes starting with a one-page "RL basics" guide on their website neatrl.com.
The first note, "De-jargonification of RL," explains core concepts with diagrams and tables: the agent-environment loop, the distinction between state (complete description of the world) and observation (partial description), actions, and rewards — friendly to both first-time readers and those seeking a refresher.
The author plans to cover everything up to the latest RL techniques, with from-scratch implementations and experiments coming in following days.
