Prerequisites:

The course requires basic knowledge from analysis (sequences, series, Riemann integration), linear algebra, probability, statistics and signals and systems (convolution, Fourier series, Fourier transform, power spectral density) 
Target skills and knowledge:

This course, addressed to the most theoretical part of Information Engineering, aims at leading the students to comprehend and employ the key mathematical tools of the field. It is expected that, at the end of the course, students understand the following concepts and use the following tools:
1.Complete and separable metric spaces;
2.Normed vector spaces;
3. Linear and continuous functionals and operators on infinite dimensional vector spaces;
4. Hilbert spaces;
5. Abstract integration;
6. Various types of convergence;
7.Calculus of variations, EulerLagrange equations;
8. Elements of convex analysis and abstract optimization;
9. Maximum entropy problems;
10. Elements of Markov chains.
At the end of the course, students are also expected to be able to apply the above listed concepts and tools to problems of optimal control, identification, spectral estimation and inverse problems which are central in Information Engineering. 
Examination methods:

The knowledge and acquired skills are checked through written tests. There are two different ways modes:
a) pass a midterm and a final test, each of two hours. Such tests occur half way trough and at the end of the semester. They feature five questions each worth six points. The final grade is computed on the basis of the average of the scores obtained in the two tests;
b) a unique threehour written test. These tests occur during the exam sessions. Such tests feature six questions each worht five points.
In both cases, the majority of the questions is taken from those proposed or even solved in class. 
Assessment criteria:

Knowledge and acquired skills will be checked along the following evaluation criteria:
1. Completeness of acquired knowledge;
2. Comprehension of the concepts introduced in the course;
3. Capability to exemplify various properties;
4. Capability to correctly employ the acquired tools in specific cases;
5. Capability to employ the tools in relevant applications in the field of Information Engineering.

Planned learning activities and teaching methods:

The educational activities consist mainly in frontal lectures at the blackboard. These allow students to follow the presented material and readily take notes. The theoretical parts are continuously illustrated through significant examples and applications. Moreover, exercises to be solved autonomously are often proposed. Most of these exercises are then solved in class during the following lectures. There are also computer presentations on topics which require complex graphics. 
Additional notes about suggested reading:

All teacher lecture notes are made available to the students through the moodle platform. Further material such as journal articles or lecture notes are also made available in the same fashion. Finally, indications are provided on URL sites where supplementary interesting material is available.
