Course Overview
Build Artificial Intelligence (AI) agents using Reinforcement Learning in PyTorch: DQN, A2C, Policy Gradients, +More!
Are you ready to unlock the power of Reinforcement Learning (RL) and build intelligent agents that can learn and adapt on their own?
Welcome to the most comprehensive, up-to-date, and practical course on Reinforcement Learning, now in its highly improved Version 2! Whether you're a student, researcher, engineer, or AI enthusiast, this course will guide you from foundational RL concepts to advanced Deep RL implementations — including building agents that can play Atari games using cutting-edge algorithms like DQN and A2C.
What You’ll Learn
Core RL Concepts: Understand rewards, value functions, the Bellman equation, and Markov Decision Processes (MDPs).
Classical Algorithms: Master Q-Learning, TD Learning, and Monte Carlo methods.
Hands-On Coding: Implement RL algorithms from scratch using Python and Gymnasium.
Deep Q-Networks (DQN): Learn how to build scalable, powerful agents using neural networks, experience replay, and target networks.
Policy Gradient & A2C: Dive into advanced policy optimization techniques and learn how actor-critic methods work in practice.
Atari Game AI: Use modern libraries like Stable Baselines 3 to train agents that play classic Atari games — from scratch!
Bonus Concepts: Explore evolutionary methods, entropy regularization, and performance tuning tips for real-world applications.

This is amazing. I learned so much with this course and I finally after many years of studying ML felt confident with writing RL code. Thank you Lazy Programmer. :)

Very precise in the theory. You can skip a lot of the lessons, if you are familiar with computer science/machine learning from your bachelor or master degree.
