The exam will be held online on the 420AA Data Mining course channel only at the request of the student in accordance with current legislation. ** When: ** The dates relating to the start of the three exams are/will be published on the online platform https://esami.unipi.it/. Within each session, we will identify dates and slots in order to distribute the various orals. The dates and slots to take the exam will be published on the course page by the end of May. Each student must also register on https://esami.unipi.it/. The examination can only be carried out after the delivery of the project. The project must be delivered one week before when you want to take the exam. Group oral discussions will be preferred in respect of the project groups in order to parallelize any discussion on the project. It is not mandatory to take the oral exam together with the other members of the group. In the event that the oral exam is not passed, it will not be possible to take it for 20 days. If the project is not considered sufficient, it must be carried out again on a new dataset or a very updated version of the current one. ** What: ** The oral test will evaluate the practical understanding of the algorithms. The exam will evaluate three aspects. - Understanding of the theoretical aspects of the topics addressed during the course. The student may be required to write on formulas or pseudocode. During the explanations, the student can use pen and paper (if online, the student can use the Miro graphic system https://miro.com/ during the explanations) - Understanding of the algorithms illustrated during the course and their practical implementation. You will be asked to perform one or more simple exercises. The text will be shown on the teacher's screen and / or copied to Miro. The student will have to use pen and paper (if online by Miro https://miro.com/ to show how the exercise is solved. - Discussion of the project with questions from the teacher regarding unclear aspects, questionable steps or choices. ** Final Mark: ** for 12-credit exam, the final mark will be obtained as the average mark of DM1 and DM2. **Exam Booking Periods** * Exam portal link: [[https://esami.unipi.it/|here]] * 1st Appello: 11/12/2022 00:00 - 05/01/2023 23:59 * 2nd Appello: 01/01/2023 00:00 - 26/01/2023 23:59 * 3rd Appello: 01/05/2023 09:00 - 26/05/2023 23:59 * 4th Appello: 22/05/2023 09:00 - 16/06/2023 23:59 * 5th Appello: 1/06/2023 09:00 - 06/07/2023 23:59 * 6th Appello: 30/07/2023 09:00 - 24/08/2023 23:59 **Exam Booking Agenda** * Agenda DM1 Link: [[https://agende.unipi.it/pjt-lpe-dhl|here]] * Agenda DM2 Link: [[https://agende.unipi.it/nkn-yan-obc|here]] * 1st Appello: starts 10/01/2023 - Room: X1 * 2nd Appello: starts 31/01/2023 - Room: X1 * 3rd Appello: starts 31/05/2023 - Room: X1 * 4th Appello: starts 21/06/2023 - Room: X1 * 5th Appello: starts 11/07/2023 - Room: X1 * 6th Appello: starts 29/08/2023 - Room: X1 & X2 **Do not forget to make the evaluation of the course!!!** ===== Exam DM1 ====== The exam is composed of two parts: * An **oral exam**, that includes: (1) discussing the project report; (2) discussing topics presented during the classes, including the theory and practical exercises. * A **project**, that consists in exercises requiring the use of data mining tools for analysis of data. Exercises include: data understanding, clustering analysis, pattern mining, and classification (guidelines will be provided for more details). The project has to be performed by min 2, max 3 people. It has to be performed by using Python or any other data mining software. The results of the different tasks must be reported in a unique paper.

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. ** //Data, data everywhere.
