"Open problems in distributed adaptive signal processing for wireless acoustic sensor networks"
Speaker: Alexander Bertrand, Department of Electrical Engineering, ESAT-SCD/SISTA (promoter: Prof. Marc Moonen)
Discussant: Moritz Diehl
The goal of this presentation is twofold. Firstly, there is an informative aspect: the general context of signal processing in wireless sensor networks will be described, with a main focus on distributed estimation. Some state-of-the-art distributed estimation algorithms will be addressed, with emphasis on the D-LMS algorithm, which is developed in a distributed optimization framework with explicit consensus constraints. The second goal is to initiate a discussion between the optimization audience on the one hand, and the DSP audience on the other hand. Therefore, some open problems from the DSP field will be described, which might be tackled from a (distributed) optimization viewpoint. The focus is on target applications with wireless (acoustic) sensor networks, particularly on target localization/tracking and SIMO channel identification.
Two OPTEC professors have been awarded three "Gouden Krijtjes", the yearly teaching awards given by the organization of engineering students (vtk). Prof. Lombaert was awarded the prize for the best course in civil engineering, and Prof. Diehl the prizes for the best professor and the best course in mathematical engineering (where he teaches numerical optimization). They received these awards at the yearly "proffentap" where experienced students taught them how to draft beer professionally.
