This course introduces some fundamental tools for statistical signal and image processing. These information-processing techniques are of interest in many practical problems.
Mean Square Linear Estimation:
• Adaptive algorithms, principles: convergence speed, tracking
• Stochastic approximation (LMS). RLS.
• Some applications: noise reduction, prediction and identification.
State models:
• Second order stationary processes: white noise, ARMA models
• Wiener estimation
• State Representation
• Kalman
• Sequential Monte Carlo methods.
The « Sum-product » algorithm and some of its applications:
• Recursive marginalization of a product of functions.
• Message passing algorithm.
• Exact solutions for finite dimensional messages:
o Linear cases for Markov chains:
• Kalman filtering and smoothing – Application to tracking.
• BCJR Algorithm – Application to turbo-codes.
• Viterbi Algorithm – Maximum Likelihood Sequence Estimation.
