   Jan 29, 2021 · Deep Reinforcement learning has been a rising field in the last few years. A good approach to start with is the value-based method, where the state (or state-action) values are learned. In this post, a comprehensive review is provided where we focus on Q-learning and its extensions. Dr Barak Or. Follow.

   Mark Towers. This tutorial shows how to use PyTorch to train a Deep Q Learning (DQN) agent on the CartPole-v1 task from Gymnasium. You might find it helpful to read the original Deep Q Learning (DQN) paper. Task. The agent has to decide between two actions - moving the cart left or right - so that the pole attached to it stays upright.

   Jan 7, 2024 · Policy-based methods: The agent learns the optimal policy, which maps states to actions to maximize rewards over time. Common policy-based algorithms include policy gradient and actor-critic. Value-based methods: The agent learns the value function, which represents the expected cumulative rewards from any given state.

   Are policy-based reinforcement learning methods better than value-based methods?

   • Policy-based reinforcement learning methods have some key advantages over value-based methods: Policy-based methods can handle larger, more complex environments with continuous action spaces better. They learn a policy that maps states to actions directly, allowing them to scale and explore effectively.

   What are reinforcement learning algorithms?

   • Reinforcement learning (RL) algorithms can be broadly categorized into two approaches: policy-based methods and value-based methods. In policy-based RL, the goal is to directly learn the optimal policy, denoted as π*. The policy defines the agent's behavior, specifying which action to take in each possible state.

   How do policy and value functions work together in reinforcement learning?

   • So in reinforcement learning, policy and value functions work together to optimize the agent's decisions and rewards over the long run. The policy maps states to actions, while the value function evaluates the quality of state and state-action pairs to guide better policies. Why would you use a policy-based method instead of a value-based method?
