Mid-term Project

A project consists in data analyses based on the use of data mining tools. The project has to be performed by a team of 2/3 students. It has to be performed by using Python. The guidelines require to address specific tasks. Results must be reported in a unique paper. The total length of this paper must be max 20 pages of text including figures. The students must deliver both: paper (single column) and well commented Python Notebooks.

  • First part of the project consists in the assignments described here: Project Description
    • Dataset: Dataset
    • Deadline: the fist part has to be delivered within November, 5th 2021 15th 2021.Send an email to: and
  • Second part of the project consists in the assignment Task 3 described here: Updated Project Description
  • * Deadline: 5th January 2022

Paper Presentation (OPTIONAL)

Students need to present a research paper (made available by the teacher) during the last week of the course. This presentation is OPTIONAL: Students that decide to do the paper presentation can avoid the oral exam with open questions. They only need to present the project (see next point). The paper presentation can be done by the group or by a single person.

Oral Exam

  • Project presentation (with slides) – 10 minutes: mandatory for all the students
  • Open questions on the entire program: optional only for students opting for paper presentation.

Reading About the "Data Scientist" Job

… a new kind of professional has emerged, the data scientist, who combines the skills of software programmer, statistician and storyteller/artist to extract the nuggets of gold hidden under mountains of data. Hal Varian, Google’s chief economist, predicts that the job of statistician will become the “sexiest” around. Data, he explains, are widely available; what is scarce is the ability to extract wisdom from them.
