Q Learning Algorithm Python

In this reinforcement learning tutorial, we explain the main ideas of the Q-Learning algorithm, and we explain how to implement this algorithm in Python. To test the algorithm, we use the Cart Pole OpenAI Gym or Gymnasium environment. The GitHub page with all the codes presented in this tutorial is given here. The YouTube video accompanying this tutorial is given below.

Q-learning is one of the easiest Reinforcement Learning algorithms. The problem with Q-learning however is, once the number of states in the environment are very high, it becomes difficult to implement them with Q table as the size would become very, very large.

Welcome to a reinforcement learning tutorial. In this part, we're going to focus on Q-Learning. Q-Learning is a model-free form of machine learning, in the sense that the AI quotagentquot does not need to know or have a model of the environment that it will be in. The same algorithm can be used across a variety of environments. For a given environment, everything is broken down into quotstatesquot and

In this article, we will delve deep into implementing a reinforcement learning agent using Q-learning, one of the simplest yet effective reinforcement learning algorithms.

Q-Learning in Python Introduction In this tutorial, we'll implement Q-Learning, a foundational reinforcement learning algorithm, in Python using the OpenAI Gym library. Q-Learning is a popular method for training agents to make decisions in environments with discrete states and actions. Our agent will learn to maximize its rewards by exploring and exploiting different strategies over time.

DQN algorithm Our environment is deterministic, so all equations presented here are also formulated deterministically for the sake of simplicity. In the reinforcement learning literature, they would also contain expectations over stochastic transitions in the environment.

Q-Learning is a popular model-free reinforcement learning algorithm that helps an agent learn how to make the best decisions by interacting with its environment.

The Q-learning iteration where is the learning rate, an important hyperparameter that we need to tune since it controls the convergence. Now, we would start implementing the Q-Learning algorithm. But, we need to talk about the exploration-exploitation trade-off. But Why? In the beginning, the agent has no idea about the environment.
