3.1. Deep Reinforcement Learning In reinforcement learning, an agent interacting with its environment is attempting to learn an optimal control pol-icy. At each time step, the agent observes a state s, chooses an action a, receives a reward r, and transitions to a new state s0. Q-Learning is an approach to incrementally esti- Helicopter Pilots.
