Actor Critic Methods
overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
Actor-Critic methods are a class of reinforcement learning algorithms that combine the benefits of both policy-based and value-based approaches. They involve training an actor to select actions based on a learned policy and a critic to evaluate the chosen actions.
Key Features
- Combines policy-based and value-based approaches
- Updates both actor and critic network parameters
- Suitable for continuous action spaces
Pros
- Efficient in handling high-dimensional continuous action spaces
- Balances exploration and exploitation effectively
- Can handle non-stationary environments well
Cons
- May suffer from instability during training
- Requires careful tuning of hyperparameters
