Course description and aims

After reviewing Fourier analysis, Sampling theorem and Discrete time Fourier transform as the common languages in signal processing, the instructor first introduces first several classical solutions, e.g., Generalized inverses and Best Linear Unbiased Estimator, for the linear inverse problems based on the orthogonal projection theorem and the singular value decomposition. Next, the instructor presents a unified view for many adaptive filtering algorithms and/or Online learning algorithms based on the convex projection theorem and fixed point theorems in Hilbert space. The instructor also introduces powerful ideas in fixed point approximations that are common principles in convex optimization algorithms and their applications to inverse problems. Finally, the instructor introduces several advanced topics, e.g., Hierarchical convex optimization, Subspace tracking and Phase unwrapping, etc.

Student learning outcomes

Along with rapid progress in the computational technology, many powerful algorithms in modern signal processing have been established in the last two decades.
By the end of this course, students will be able to:
1) understand such algorithms in unified ways.
2) understand mathematical ideas behind such algorithms.
3) understand how such algorithms can be applied to real world problems.
