News

The laboratory will start on January 12, 2023.

Goals

This laboratory introduces the theoretical and algorithmic foundations of Reinforcement Learning, the subfield of Machine Learning studying adaptive agents that take actions and interact with an unknown environment. Reinforcement learning is a powerful paradigm for the study of autonomous AI systems, and has been applied to a wide range of tasks including autonomous driving, industrial automation, conversational agents, trading and finance, game playing, and healthcare.

Exam

The exam consists in developing an experimental project and writing a report which will be discussed in the oral exam. The discussion will also include questions on the theory covered in the course. The final grade will take into account both the project and the oral exam.
