Kevin Wilkinghoff

I am a research associate at Fraunhofer FKIE and a Ph.D. student at University of Bonn. My interests lie in machine listening and machine learning in general. Most of my recent work including my Ph.D. thesis is focused on detecting anomalous sounds and acoustic open-set classification problems.
