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

Unique edition

Responsible
Lesson period
First trimester
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.
Assessement methods and criteria
The 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 first examination session, the student may choose instead to take 3 midterm exams.
The outcomes of the tests will be available in the SIFA service through the UNIMIA portal and on the web site of the course.
