ASC - Approximation, sampling and compression in data science

In these lectures I will present an introduction to compressed sensing and sparse approximation.  The first lecture gives an overview of compressed sensing and its standard theory.  Next, I will focus on two major areas of application.  The second lecture considers image reconstruction, and its application to medical and scientific imaging.  The third lecture considers high-dimensional approximation via compressed sensing, with application to parametric PDEs in Uncertainty Quantification.
