Reddit user East-Muffin-6472 is sharing notes from a "learning RL from scratch" journey; the first one-page RL basics post is live on neatrl.com.
- Explains core concepts with light math: agents learn by trial and error, improving a policy as cumulative reward grows over time
- Clarifies state vs. observation (complete description of the world vs. partial snapshot)
- Includes agent-environment interaction diagrams; suited for first-time readers or refreshers
The author plans to continue up to modern RL with from-scratch implementations and experiments.
