40720 - DATA MINING

Conoscenze e abilità da conseguire

This course will present main statistical methods used in knowledge discovery in business databases; special attention will be paid to techniques that help to single out the relationships of interdependence and patterns in business phenomena. In particular, this course seeks to enable the student: - to correctly plan a data mining process; - to choose the best suited statistical methodology for the problem at hand; - to critically interpret empirical results; - to use these results in the business decision process.

Modalità di verifica e valutazione dell'apprendimento

FOR ATTENDING STUDENTS:

Exam is a combination of:

1) quiz on EOL/Zoom, including multiple choices, STATA output to be interpreted and questions on all the topics included in the syllabus, (20 points)

2) four weekly works by groups (during the lectures), including comprehension of scientific articles and the analysis of (real) datasets (12 points, 3 points for each assignment)

The grading of the QUIZ is as follows:

< 11: not sufficient (exam failed)

11-12: sufficient

13-14: satisfactory

15-16: good

17-18: very good

19-20: excellent

The grading of each ASSIGNMENT is as follows:

• 3: the report provided reveals an exhaustive and complete mastery of the topic covered in the course and a consistent execution ability with any minor inaccuracies;
• 2: from the weekly report it emerges an appreciable degree of knowledge of the topic covered in the course and a good ability of execution;
  
• 1: the work provided for the homework shows significant methodological or theoretical inaccuracies or significant analytical imperfections, which show just sufficient ability of execution;
• 0: inadequate or wrong.

Laude will be given if the sum of the two parts is equal or greater than 31.

 

FOR NOT ATTENDING STUDENTS:

Exam is a combination of:

1) quiz on EOL/Zoom, including multiple choices, STATA output to be interpreted and questions on all the topics included in the syllabus, (20 points)

2) ORAL exam (12 points).

The grading of the QUIZ is described above.

The grading of the ORAL is as follows:

• 10-12: answer correct, exhaustive, complex, which highlights the complete mastery of the topics covered in the course and a consistent execution ability with any minor inaccuracies;
• 7-9: answer not entirely correct and/or incomplete, from which emerges an appreciable degree of knowledge of the topics covered in the course and a good ability of execution;
• 6: answer with significant methodological or theoretical inaccuracies or significant analytical imperfections, which show just sufficient ability of execution;
• 0-5: answer inadequate or wrong.

Laude will be given if the sum of the two parts is equal or greater than 31.

The graduation of the final grade is as follows:

• 18-19: knowledge of a very limited number of topics covered in the course and analytical skills that emerge only with the help of the teacher, expressed in an overall correct language;
• 20-24: knowledge of a limited number of topics covered in the course and ability to autonomous analysis only on purely executive matters, expression in correct language;
• 25-29: good knowledge of a large number of topics covered in the course, ability to make independent choices of critical analysis, mastery of specific terminology;
• 30-30L: Excellent knowledge of the topics covered in the course, ability to make autonomous choices of critical analysis and connection, full mastery of specific terminology and ability to argue and self-reflection.
