Years ago, my colleague Rene Grzeszick and I began collaborating on Acoustic Event Detection (AED) using the Bag-of-Features (BoF) method. It all started because I wanted to exclude footsteps and sounds of moving devices on a table in my speaker localization a geometry calibration methods. After our first joint paper became one of our most cited, we continued to refine and apply the method.
Among other things, I managed to apply it for speech enhancement with Sharon Gannot during my stay at the Department of Electrical Engineering, Bar Ilan University, Ramat Gan, Israel.
Later, I was happy to present our extension for Acoustic Sensor Networks (ASNs) at the fabulous DCASE 2016 Workshop in Budapest, Hungary.
I am happy to announce that the current state of the development along with some extensive evaluation can now be found in a journal paper. We even made it on the cover 😉
