This page provides an overview of the various examples of strategy gradient methods in the domain of Deep Reinforcement Learning (DRL). Strategy gradient methods are a class of reinforcement learning algorithms that optimize the policy directly by learning a strategy function.
Key Concepts
- Strategy Gradient: Strategy gradient methods learn a probability distribution over actions directly, rather than learning a value function or a policy.
- Examples: Some popular examples of strategy gradient methods include the actor-critic approach and the policy gradient method.
Common Examples
Here are some common examples of strategy gradient methods used in DRL:
- Asynchronous Advantage Actor-Critic (A3C): This method combines asynchronous training with actor-critic methods and is known for its efficiency in learning complex policies.
- Proximal Policy Optimization (PPO): PPO is a policy gradient method that uses a clipped surrogate objective to ensure stability during training.
