| | * the first session of exams (i.e., first "appello") will be on __January 16th, 09:00, room C29 (aula Faedo)__ at [[https://hiis.isti.cnr.it/images/how_to_reach_room_c29.jpg | ISTI-CNR]]. Bring your identity card (or passport) for identification. |
| | * the second session of exams will be held on three days: __February 7 at 10:00__, __February 10 at 9:00__, __February 12 at 9:00__. Room: Aula C-29 "A. Faedo" ([[https://hiis.isti.cnr.it/images/how_to_reach_room_c29.jpg | ISTI-CNR]]). Bring your identity card (or passport) for identification. Interested students should have received the detailed calendar of exams. Contact the teachers in case of issues. |
| | * the third session of exams will be held on __April 1st at 10:00__ in Aula C-38 (office of prof. Nanni) at [[https://hiis.isti.cnr.it/images/how_to_reach_room_c29.jpg | ISTI-CNR]]. |
| | |
| | **__Instruction for the exam__**: The exam will consist of a combination of general concept questions and short, specific questions. The questions may span the entire course content, testing your understanding of the key topics. Additionally, we will present a problem and ask you to work through the reasoning process for its solution. You will then be required to implement the solution by writing Python code "live", similar to the approach we used in the practical sessions during the course. During this part of the exam, you will be able to use resources such as Google and ChatGPT to assist with coding, reflecting the collaborative and problem-solving nature of the course. |

| The analysis of geographic information, such as those describing human movements, is crucial due to its impact on several aspects of our society, such as disease spreading (e.g., the COVID-19 pandemic), urban planning, well-being, pollution, and more. This course will teach the fundamental concepts and techniques underlying the analysis of geographic and mobility data, presenting data sources (e.g., mobile phone records, GPS traces, geotagged social media posts), data preprocessing techniques, statistical patterns, predicting and generative algorithms, and real-world applications (e.g., diffusion of epidemics, socio-demographics, link prediction in social networks). The course will also provide a practical perspective through the use of advanced geoanalytics Python libraries. | The analysis of geographic information, such as those describing human movements, is crucial due to its impact on several aspects of our society, such as disease spreading (e.g., the COVID-19 pandemic), urban planning, well-being, pollution, and more.
