Reinforcement Learning

Reinforcement Learning (RL) is a machine learning training paradigm where an agent learns to make decisions by performing actions in an environment to maximize cumulative rewards. The agent learns through trial-and-error feedback.

Frequently Asked Questions

What is the agent-environment loop in RL?

The agent observes the environment state, chooses an action, receives a reward or penalty, and transitions the environment to a new state.

What is the difference between supervised learning and RL?

Supervised learning trains on correct answers. RL trains on feedback (rewards or penalties) without direct labels.
