Jul 4, 2024 · Q-learning is a popular model-free reinforcement learning algorithm used in machine learning and artificial intelligence applications. It falls under the category of temporal difference learning techniques, in which an agent picks up new information by observing results, interacting with the environment, and getting feedback in the form of rewards.
You’ll explore more about how reinforcement learning works with code examples. In this tutorial, we will learn about Q-learning and understand why we need Deep Q-learning. Moreover, we will learn to create and train Q-learning algorithms from scratch using Numpy and OpenAI Gym.
Sep 3, 2018 · Q-Learning is a value-based reinforcement learning algorithm which is used to find the optimal action-selection policy using a Q function. Our goal is to maximize the value function Q. The Q table helps us to find the best action for each state.
Reinforcement learning involves an agent, a set of states , and a set of actions per state. By performing an action , the agent transitions from state to state. Executing an action in a specific state provides the agent with a reward (a numerical score). The goal of the agent is to maximize its total reward.
Nov 27, 2020 · The Q-learning algorithm uses a Q-table of State-Action Values (also called Q-values). This Q-table has a row for each state and a column for each action. Each cell contains the estimated Q-value for the corresponding state-action pair.
Dec 12, 2020 · In the Q-Learning algorithm, the goal is to learn iteratively the optimal Q-value function using the Bellman Optimality Equation. To do so, we store all the Q-values in a table that we will update at each time step using the Q-Learning iteration: The Q-learning iteration.
May 15, 2024 · Q-learning is a reinforcement learning algorithm that finds an optimal action-selection policy for any finite Markov decision process (MDP). It helps an agent learn to maximize the total reward over time through repeated interactions with the environment, even when the model of that environment is not known. How Does Q-Learning Work? 1.
Nov 14, 2019 · Reinforcement Learning is the science of making optimal decisions using experiences. Breaking it down, the process of Reinforcement Learning involves these simple steps: Observation of the environment. Deciding how to act using some strategy. Acting accordingly. Receiving a reward or penalty. Learning from the experiences and refining our strategy.
May 18, 2022 · So today, we're going to dive deeper into one of the Reinforcement Learning methods: value-based methods and study our first RL algorithm: Q-Learning. We'll also implement our first RL agent from scratch: a Q-Learning agent and will train it in two environments:
