Learning outcomes

At the end of the course the student knows and understands: - the principles and the most relevant use cases of a wide set of Machine Learning algorithms which are used to extract relevant and actionable information from large amounts of data - the main issues in the analysis and manipulation of Big Data - the main frameworks available for Big Data In particular, the student can: - design the main steps of a Data Mining process - choose the Machine Learning methods best suited for the process - evaluate the quality of the result in order to support strategic and operational decisions.

Teaching methods

Most course lectures are in "traditional" classrooms and exploit the slides. Case studies are also proposed based on open-source software.

Interaction is also stimulated with the use of consultation tools, such as Kahoot!

The laboratory activity for module 1 will be an integral part of the learning process.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 on Health and Safety online

Assessment methods

Module 1

Verification of knowledge is tested through multiple choice questions, administered with the IoL system. The minimum to pass is to answer correctly half + 1 of the questions. The weight of this part is 50%.

The verification of abilities will be tested in lab with the development of a program for the execution of a Machine Learning task on an assigned data set. The quality of the solution will be evaluated on the basis of the correctness of the approach, the correctness of the solution, the quality of the coding and of the documentation. The minimum to pass is to give a sensible approach and a reasonable coding. The weight of this part is 50%.

It is also possible, on request, to have an oral examination, with possible outcomes -1="no answer", 0="some general knowledge", +1="correct answer", and weight 10%.

Module 2

The assessment is mainly oriented to knowledge, it will be administered with Virtuale and consists of 8 multiple choice questions plus one open question on the topics listed above. The duration is 30 minutes.

Additional details on Assessment are available in the Virtual Learning Environment

Teaching tools

  • Projection of slides made available before the lectures
  • Kahoot! [https://kahoot.com/] for class interaction
  • IoL (Moodle) for distribution of teaching materials, self-evaluation activities, exams
  • Python [https://www.python.org/]
