# Exams

**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 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 25 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 by**November 19th, 2024**. The delivery will be through Teams' assignement

- Second part of the project consists in the assignment described here:
**Deadline**: Dec 29, 2024

Students who did not deliver the above project within **Dec 29, 2024** need to ask by email a new project to the teachers. The project that will be assigned will require about 20 days of work and after the delivery it will be discussed during the oral exam.

** 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 on the entire program. They only need to present the project (see next point) and answer open question only on the topics which will not be covered by the project. The paper presentation can be done by the group or by a single person.

**Oral Exam**

**Project presentation**(with slides) – 15 minutes: mandatory for all the students with question fo understanding the details of any part of the project.**Open questions on the entire program**: for students who will not opt for paper presentation**Open questions on the topics which will not be covered by the project**only for students opting for paper presentation.- Group presentations of the project are preferred. If this is impossible please contact me for finding a solution.

**How to book for the exam colloquium? **

In https://esami.unipi.it/ you can find the dates for the exam: one for January and one for February. Each student must do the registration on one of the 2 dates. These are not the dates of the colloquium or project delivery but we will use the list of registered students for organizing the exam dates. After that deadline we will share with you a calendar for the oral exam.
