Christian Goerick , "Towards Cognitive Robotics", Creating Brain-like Intelligence, Springer Verlag, 2008.
AbstractIn this paper we review our research aiming at creating a cognitive humanoid. We describe our understanding of the core elements of a processing architecture for such kind of an artifact. After these conceptual considerations we present our research results on the form of the series of elements and systems that have been researched and created....

Holger Brandl, Frank Joublin, Christian Goerick , "Towards unsupervised online word clustering", Proc. International Conference on Acoustics, Speech, and Signal Processing (ICASSP), 2008.
AbstractUnderstanding the bootstrapping process of speech representation in infants is one key issue towards systems which may provide human-like speech recognition abilities some day. Until now, almost all current speech recognition systems have failed to integrate learning into the recognition process. Here we propose a system for unsupervised word-clustering, which is able to recognize and learn the structure of speech online in a unified framework. T...

Martin Ernst Heckmann, Claudius Gläser, Miguel Vaz, Tobias Rodemann, Frank Joublin, Christian Goerick , "Listen to the Parrot: Demonstrating the Quality of Online Pitch and Formant Extraction Via Feature-Based Resynthesis", Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), pp. 1699-1704, 2008.
AbstractWe present a system for online extraction of the fundamental frequency and the first four formant frequencies from a speech signal. To evaluate the performance of the extraction a resynthesis of the speech signal is performed. The resynthesis is based on the extracted frequencies and the energy of the input signal at the formant locations. The extraction of the fundamental frequency and the formants is robust against room echoes and interfering n...

Volker Willert, Julian Eggert, Mark Toussaint, Edgar Körner , "Probabilistic Exploitation of the Lucas and Kanade Smoothness Constraint", Machine Learning and Applications, 2008.
AbstractThe basic idea of Lucas and Kanade is to constrain the local motion measurement by assuming a constant velocity within a spatial neighborhood. We reformulate this spatial constraint in a probabilistic way assuming Gaussian distributed uncertainty in spatial identification of velocity measurements and extend this idea to scale and time dimensions. Thus, we are able to combine uncertain velocity measurements observed at different image scales and p...

AbstractThere are two elementary building blocks whose intimate relationship has been overlooked so far: The cortical column as ubiquitous local processor underlying all cognitive operations and the Bayesian framework with the generic operation of calculating posterior probabilities given likelihoods and prior probabilities. In this contribution we try to bridge this gap by providing a detailed mapping between parts of the cortical column and processing ...
