Reinforcement Learning Explained: MDP, Q-Learning & Deep RL Internals
Reinforcement learning is quietly powering some of the most jaw-dropping achievements in modern AI — AlphaGo defeating world champions, ChatGPT being fine-tuned with human preferences via RLHF, robotic hands solving Rubik's cubes in the dark. What makes RL different from supervised learning isn't just a technique — it's a fundamentally different relationship between the learner and the world. The agent has no labeled dataset to learn from. It must discover what's good by doing, failing, and adapting in real time.
What is Reinforcement Learning Basics?
Reinforcement Learning Basics is a core concept in ML / AI. Rather than starting with a dry definition, let's see it in action and understand why it exists.
