The course will include 30 hours of lectures and 50 hours of laboratory. The lectures will focus both on theoretical and practical aspects of the course topics and will include open discussions aimed at developing suitable solutions for different problems. The course includes laboratory sessions on data science processes and machine learning algorithms for engineering applications. The laboratories will allow the students to apply the methods presented during lectures to real data, with a particular focus on networking applications. Students will prepare a written report on a group project assigned during the course.

Copies of the slides used during the lectures, exercises, and manuals for the activities in the laboratory will be made available. All teaching material is downloadable from the course website or the teaching Portal. Suggested books: [1] A.

Exam: Written test; Individual project; Group project;

The exam includes two mandatory parts. The two mandatory parts are (i) a written exam and (ii) the evaluation of a group project. The final score is defined by considering both the evaluation of the group project and the written part. The teacher may request an integrative oral test to confirm the obtained evaluations. The written examination lasts 90 minutes and will consist of open questions covering the topics presented during the lectures. Textbooks, notes, and electronic devices of any kind are not allowed. The written examination will assess: • The theoretical understanding of the basic principles of the presented machine learning approaches • The knowledge and understanding of the different approaches that have been presented during the lectures • The ability of the student to critically analyze and evaluate different case study and example of networking application of ML. • The ability of the students to design, implement and evaluate code in the Python language and its ML libraries The projects will address machine learning tasks. For each project, a dataset will be provided, and the students will have to develop a pipeline using suitable models for the specific task based on the topics and tools presented during lectures and laboratories. Each group will have to provide a technical report detailing the employed methodology and a critical analysis of the obtained results. The report will assess: • The degree of understanding of the theoretical principles of different machine learning approaches • The ability of the student to analyze a specific problem, assessing which approaches, among those that have been presented, are more suited to solve the task • The working knowledge of the Python language and the major data mining and machine learning libraries • The ability of the student to apply the studied methods to devise suitable solutions for the specific case study • The ability of the student to critically evaluate the effectiveness of the proposed approaches The final grade will be given by the weighted average of the written exam (40%) and the project report grade (60%). Each part will have a grade between 0 and 30 cum laude. Both parts must be sufficient to pass the exam. • Individual written exam (40%, at least 18/30) • Project (60%, at least 18/30)

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
