Frequently asked questions
What is reinforcement learning?
Reinforcement learning involves training agents through trial and error by having them interact with an environment and receive rewards for their actions.
In what paradigm does a machine learning agent learn?
A machine learning agent learns through this paradigm by interacting with its environment via trial-and-error, receiving rewards when it performs beneficial actions.
How do deep neural networks enable reinforcement learning to work?
Deep neural networks allow reinforcement learning to process high-dimensional observations like images, facilitating representation learning and enabling agents to understand complex visual information.
What is a value-based method that learns the Q-function?
A value-based method learns the Q-function, Q(s,a) = expected return from state s after executing action a. The optimal policy is then determined by maximizing this Q-value.
