Foundations of Reinforcement Learning with Python

How do machines learn to make optimal decisions in complex, dynamic environments? Reinforcement learning provides the framework for training intelligent agents through trial and error, mimicking how humans learn from consequences. This text-based course guides you from the fundamental mathematics of decision-making to implementing your first self-learning agents. You will gain a solid intuitive and practical grasp of agent-environment interactions, reward structures, and policy optimization using modern Python tools. What you'll learn: - Understand the fundamental Markov Decision Process framework, including states, actions, rewards, and discount factors. - Implement the classic Q-learning algorithm from scratch using clean, modern Python code. - Configure simulated environments using the industry-standard Gymnasium library to train and test your agents. - Apply exploration-exploitation strategies, such as epsilon-greedy, to balance agent learning. - Analyze agent performance by tracking rewards and training progress through written code examples. You will start with core theoretical definitions and the mathematics of rewards before moving into step-by-step code implementations of model-free algorithms. The material progresses logically from basic grid-world simulations to structured agent evaluation. This course is designed for aspiring AI developers, data analysts, and software engineers who are new to reinforcement learning but have a basic understanding of Python programming.
