Mathematics Colloquium

From biomedical imaging to online blogs: Graph signal processing

Speaker: Jelena Kovacevic, NYU, Dean of Tandon

Location: Warren Weaver Hall 1302

Date: Monday, November 5, 2018, 3:45 p.m.


 I will present a path from classification in biomedical imaging to online blogs, where a common thread is graph signal processing, a theoretical framework that generalizes fundamental concepts of classical signal processing from regular domains, such as lines and rectangular lattices, to general graphs. It is particularly applicable to domains such as physical, engineering, and social, where signals are characterized by irregular structure. Signal processing on graphs has found multiple applications, including approximation, sampling, classification, inpainting and clustering, and I will describe some of these.
