Contact Please do not send emails to our personal email addresses. Instead, use the following points of contact:
  • Actively participate during the lectures and exercise sessions.
  • Use GitLab issues for questions regarding lectures, exercises, and projects. Always add the label(s) corresponding to your issue.
  • For personal or confidential questions create a confidential issue on Gitlab.
  • If you do not have access to Gitlab, or in case of other problems preventing you from creating an issue on Gitlab, send an email to marc.wyss@inf.ethz.ch. Please only use the email option if creating a GitLab issue is not possible.
Teaching All teaching will be in person. However, recordings will be made available. Besides at the exam, no attendance is required to pass this course.
Lectures

  • Thursday, 14:15‒16:00, HG D7.2
Feel free to select the exercise session that suits you best. On Tuesdays, RZ F21 typically has available seats, whereas ML H44 tends to be crowded. We recommend not only considering ML H44 but also RZ F21 for a more comfortable experience.
Exam Written computer exam. The exam will take place in the period between August 5 to August 30; the exact date is yet to be determined and will be announced around end of June.
Project The course includes two optional coding projects. Projects have to be completed individually and allow to gain a bonus of up to 0.25 to the final grade. Achieving the highest grade is also possible without completing the projects.
More information will be provided in the lectures.
