Abstract: In reinforcement learning, we aim at designing agents that take sequential decisions in unknown environments by learning through their own interaction with such environments. However, learning from scratch is often costly in terms of data to collect, transfer learning can help to overcome some of those difficulties by reusing previously learned knowledge. Jointly, designing more data efficient algorithms is also important to scale to more real world problems. During the presentation, our contributions to these two aspects will be introduced. Besides, as the operations of autonomous systems generally affect simultaneously several users, it is crucial that their designs account for fairness considerations. Hence, we also investigated the problem of learning a policy that treats its users equitably in single and multi-agent cases.
