Teaching methods

Frontal lectures in classroom.

During the course, some examples in MATLAB and/or Python related to the discussed technologies will be provided. The code will be made available to the students to further explore these aspects.

Assessment methods

The assessment is performed through a written test and an oral presentation.

The written test is composed of both open and closed questions with 10-12 questions, to be answered in 90 minutes. For the oral presentation, students shall focus on a specific topic: each student prepares a presentation for the final exam discussing the selected topic with proper detail. During the final exam, the written test will also be discussed if needed.

Teaching tools

Slides and support MATLAB/Python code provided on VLE.
