Deep Reinforcement Learning
Deep Reinforcement Learning (DRL) is a subfield of machine learning that combines reinforcement learning principles (agents, actions, rewards) with deep neural networks to learn decision-making policies for high-dimensional state spaces.
Frequently Asked Questions
What role does the deep neural network play in DRL?▼
It acts as a function approximator, mapping high-dimensional inputs (like image pixels or sensor arrays) directly to action value probabilities.
What is the difference between Q-learning and Deep Q-Networks (DQN)?▼
Q-learning stores state-action values in a static table, which fails for large spaces. DQN uses neural networks to predict those values.
