A scientific paper authored by one of the lecturers will be assigned to each group. During the workshops, the students will have the opportunity to interact with the author of the paper. An oral presentation of the paper by the group will be organized.

After the course, each student will prepare a technical report on a topic related to the course. The topic cannot be associated with the same lecturer as the paper presented during the workshop. This is personal work, and the topic should be approved by the lecturer during the workshop. The report should summarize the topic, provide a literature review, and a personal discussion about the topic (strengths and weaknesses, potential applications, possible extensions, etc.) The objective is to show that the students have understood the concepts, and are able to be critical about it. The report does not need to be long (about 10-15 pages).
