Prerequisites
  • LEPL1106 (or equivalent training in signals and systems)
  • LEPL1108 (or equivalent training in probabilities and statistics)
Main themes
The object of this course is to lead to a good understanding of stochastic processes, their most commonly used models and their properties, as well as the derivation of some of the most commonly used estimators for such processes : Wiener and Kalman filters, predictors and smoothers.
Aims

At the end of this learning unit, the student is able to :

1
1.1; 1.2; 1.3
3.1; 3.2; 3.3
4.2
At the end of this course, the students will be able to :
  • Have a good understanding of and familiarity with random variables and stochastic processes ;
  • Characterize and use stable processes and their spectral properties;
  • Use the major estimators, and characterize their performances ;
  • Synthetize predictors, filters and smoothers, in both Wiener or Kalman frameworks.
 
Content
  • Part 1 - Estimation: probability theory (reminder), Fisher and Bayesian estimation, bias, covariance, mean square error, Cramér--Rao bound, asymptotic properties, classical estimators (maximum likelihood, best linear unbiased, maximum a posteriori, conditional mean...), hidden Markov model, nonlinear filtering, particle filtering, Kalman filter.
  • Part 2 - Stochastic Processes and LTI Filters: complex random variables, stochastic processes, stationarity, ergodism, autocovariance, power spectral density, transformation by LTI systems, white noise, spectral factorization, finite-dimensional models (AR, MA, ARMA...), Wiener filter.
Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Learning will be based on courses interlaced with practical exercise sessions (exercises done in class or in the computer room using MATLAB). In addition, the training includes a project to be realized by groups of 2 or 3 students.
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

  • Project during the course semester
  • Exam
  • Other activities, such as quizzes and homework exercises, can be taken into account in the final grade
Precisions are given in the course outline (plan de cours) available on Moodle.

Teaching methods
If the sanitary conditions allow, courses and exercice sessions will be held in presence.
If the sanitary conditions require it, courses and exercice sessions will be organised remotely or in comodal. Students may also be invited to watch podcasts.
Evaluation methods
The evaluation will be based on the content of the courses, the exercice sessions and the project (independently on whether they are held in presence or remotely), and of the podcasts if applicable.
The evaluation will be written and individual.
The exam may consist in a combination of open and closed questions. 
If the sanitary conditions allow, the exam will be closed book. A personal summary of one two sided A4 sheet will be allowed.
If the sanitary conditions require remote examination, the examination will be open book.
The project will also be evaluated by group, on the basis of a report and of homeworks.
