Modeling data is the way we – scientists – believe that information should be explained and handled. Indeed, models play a central role in practically every task in signal and image processing. Sparse representation theory puts forward an emerging, highly effective, and universal such model. Its core idea is the description of the data as a linear combination of few building blocks – atoms – taken from a pre-defined dictionary of such fundamental elements.

This Professional Certificate program will introduce you to the field of sparse representations, starting with its theoretical foundations, and systematically present its key achievements. We will touch on theory, numerical algorithms, and applications in image processing.

The tools and algorithms presented in this program are state-of-the art in these fields, and relevant to many applications and needs, covering signal/image restoration, segmentation, sampling, compression, recognition, anomaly detection, separation, and more. 

This program is relevant to algorithm developers in machine learning and data mining. The tools learned will help developers be more effective in revealing hidden structures of given data, which is valuable for classification, clustering, stock market prediction, and more.
