This seminar on Reinforcement Learning (RL) will cover both classical approaches and modern techniques based on deep learning methods. The seminar will consist of an introductory lecture given by Prof. Carlo D'Eramo, where several topics will be described. Following this, participants will have to select a topic of their choice, and study related scientific papers, journals, etc. The examination will consist of an oral presentation and a discussion (30min + 10min), and the writing of a report on the studied material (10-15 pages). The deadline for delivering the report will be 2 weeks after the oral presentation.
