Q learning but leave room for improvement when compared to the state-based baseline. 1 Introduction Reinforcement learning (RL) is a type of unsupervised learning, where an agent learns to act optimally through interactions with the environment, which returns a next state and reward given some current state and the agent’s choice of action.

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-
