The fundamental tools of probability theory are introduced, with particular reference to their applications to stochastic processes, information theory, inference problems, and the modelling of physical systems.
The fundamental tools of probability theory are introduced, with particular reference to their applications to stochastic processes, information theory, inference problems, and the modelling of physical systems.
The student must master the fundamentals of probability theory and its applications to stochastic processes, information theory, inference problems, and the modelling of physical systems. In particular, the student must be able to understand and apply concepts of statistical independence and correlation of random variables, to understand and estimate the amount of information associated to a (set of) random variable(s), to formulate and solve problems in statistical inference, and to model physical phenomena in terms of interacting random variables.

... The examination will be based on a midterm written test and on an oral test on the course topics.
Gli studenti e le studentesse con disabilitÓ o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'UnitÓ Special Needs, al fine di permettere al/la docente la declinazione pi¨ idonea in riferimento alla specifica tipologia di esame.
The examination will be based on a midterm written test and on an oral test on the course topics.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
