Dictionary Learning – Methods and Applications (Lecture 27-04-2020 at 13:00 CET)

As per our schedule, the online monthly meeting will take place next Monday the 27th of April at 1pm CET. Dr Dimitris Ampeliotis will deliver a talk entitled “Dictionary Learning – Methods and Applications“. The abstract of the talk and a brief CV are given below.


The presentation will introduce dictionary learning (DL) methods and will briefly review the most successful algorithms employed in this task. In the sequel, several variants of DL methods will be reviewed, such as coupled dictionary learning and discriminative DL. Online and distributed DL will also be explained. Emphasis will be given to the applications of DL methods, such as in compression, denoising, inpainting, super resolution and classification tasks.
