Overview
The course provides an overview of mathematical models and algorithms behind optimal decision making in time-series systems. The course focus is on optimal decision making and control, reinforcement learning, and decision making under uncertainty.
Practical matters
Lecturer: Joni Pajarinen.
Teaching assistants (TAs): Yi Zhao, Aleksi Ikkala, Wenshuai Zhao, Nikita Kostin, Ali Khoshvishkaie, Jifei Deng, Mohammadreza Nakhaei.
- The reinforcement learning lecture will be organized in person this year.
- Location: Maarintie 8, AS1
- Time: Tuesdays 14:15-16:00 (Period I, II)
- Although in person participation is encouraged for the full lecture experience lectures will be also recorded and can be watched afterwards
- Grading Scale: 0-5
- 7 individual assignments (60%)
- 1 project work, in groups (max. 2 students) (20%)
- Quizzes (due before lecture) (20 %)
- Exercise sessions will be given twice a week. Attendance is optional.
- (Remotely) Mondays 12.15–14.00, Zoom Link (links will be given during sessions)
- (In person) Wednesdays 10.15–12.00, Maarintie 8, AS3 Saab Space
- Please join the slack channel to receive the latest updates and ask questions about the exercises. Please use your Aalto account for registering to Slack. Notice that, we will use the slack channel as the main place to answer questions about the exercises.
- Each Student has 3 days in total for late submissions.
