Metodi didattici

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.

Modalità di verifica e valutazione dell'apprendimento

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.

Strumenti a supporto della didattica

Slides and support MATLAB/Python code provided on VLE.
