Projects

Presently, I am investigating statistical models of speech signals and natural sounds using supervised and unsupervised learning algorithms. This work is largely incorporated into the DIRAC project ("Detection and Identification of Rare Auido-visual Cues") which started in January 2006.

During my Post-Doc, I worked on modeling dynamics of biomedical signal by complex ICA, see

During my Ph.D., I was working on convolutive blind source separation of acoustic signals. Most of this work, including demos, is described on my old (now unmaintained) webpages in Oldenburg:

Infos and demos for blind separation of acoustic signals.
