Learning objectives
This course aims at introducing modern and advanced mathematical techniques useful for understanding and modeling big data structures and algorithms.
Expected learning outcomes
At the end of the course the student will be able to formalize real world problems in mathematical terms and to solve simple exercises related with linear algebra, graph theory, Markov Chains, Optimization and Decision Theory.
Course syllabus and organization

Single session

Responsible
Lesson period
First trimester
The lessons will take place online in synchronous way on the platforms MSTeams or Zoom during the timetable fixed by the faculty. The lectures will also be registered and made available to the students to be followed in an asynchronous way.

The program of the course will remain unchanged.

The written exams during the emergency will maintain the same structure of the usual ones and will be organized through the platform Exam.net, with an external supervision by Zoom or MSTeams.
Prerequisites for admission
Prerequisites for this course include a good knowledge of the mathematical tools presented in Calculus I and Linear Algebra courses and in an introductory course in Probability and Statistics, with particular reference to the following arguments: real functions of one and two variables; derivatives; partial derivatives; integrals; vectors and matrices; operations between matrices; determinants; eigenvalues and eigenvectors; probability measures; events; random variables; distributions.
Assessment methods and Criteria
he final examination consists of a written exam during which the student must solve some exercises in the format of open-ended and/or multiple answer questions, with the aim of assessing the student's knowledge and ability to solve problems related with the arguments of the course. The duration of the written exam will be proportional to the number of exercises assigned, also taking into account the nature and complexity of the exercises themselves (however, the duration is usually of 1.5 Hours). In place of a single written exam given during the examination sessions, the student may choose instead to substitute the part of exam of the module on Graph Theory and Discrete Mathematics by solving a set of homeworks and small projects, that will be assigned by the teachers during the course. The homeworks are reserved to the students who follow the course in real time. The students who get a positive evaluation in the homeworks will have to pass a reduced written test only on the module of Optimization. The final grade will be the mean of the grades of the two modules.

The outcomes of the exams will be available in the SIFA service through the UNIMIA portal and on the web site of the course.
