All registered students will be asked to give a 60-min in-class presentation on a RL theory paper of their choice. The paper should either come from the provided list of papers, or upon instructor approval. Before their presentation, a student is required to schedule a meeting with the instructor to discuss their presentation materials (slides, lecture notes, etc). Throughout the course, students are highly encouraged to meet with the instructors regularly on paper choices, reading progress, etc.
Here are some useful guidelines for:
Paper presentation ideas (under construction)
Below are a few example research topics in reinforcement learning theory, each with a few “seed papers”; you can use the related work section in these papers, or use the “cited by” functionality in e.g.
google scholar to find more papers on the same topic. Please also refer to proceeding pages of recent machine learning / learning theory conferences and workshops for more presentation ideas, such as:
Courses / tutorials in the RL theory research community may also have interesting reference papers good for presentation, for example:
