Abstract: As a way of achieving artificial intelligence, machine learning is capable of solving complex problems in the real world. Different from supervised learning and unsupervised learning, reinforcement learning (RL) is concerned with how an agent adjusts its actions in order to optimize an expected long-term objective by observing the feedbacks in an unknown surrounding environment. Markov decision process (MDP) provides the mathematical framework to model the interactions between the agent and the environment. In this talk, we will first briefly introduce basics of a MDP. Through several use case studies from our most recent research efforts, we will see how RL algorithms achieve the desired objectives in wireless communications only with limited feedback information received from the network.
