Irene Ayllón Clemente, Martin Ernst Heckmann, Gerhard Sagerer, Frank Joublin , "Multiple Sequence Alignment Based Bootstrapping for Improved Incremental Word Learning", International Conference on Acoustics, Speech, and Signal Processing (ICASSP), 2010.
AbstractWe investigate incremental word learning with few training exam- ples in a Hidden Markov Model (HMM) framework suitable for an interactive learning scenario with little prior knowledge. When using only a few training examples the initialization of the models is a cru- cial step. In the bootstrapping approach proposed, an unsupervised initialization of the parameters is performed, followed by the retrain- ing and construction of a new HMM using mu...

Thomas H Weisswange, Constantin Rothkopf, Tobias Rodemann, Jochen Triesch , "Model averaging as a developmental outcome of reinforcement learning", 2010.
AbstractTo make sense of the world, humans have to rely on the information that they receive from their sensory systems. Due to noise on one side and redundancies on the other side, it is possible to improve estimates of the signal's causes by integrating over multiple sensors. In recent years it has been shown that humans do so in a way that can be matched by optimal Bayesian models (e.g. [1]). Such an integration is only beneficial for signals originat...

AbstractWe present an audio-visual attention system for speech based interaction with a humanoid robot where a tutor can teach visual properties/locations (e.g "left") and corresponding, arbitrary speech labels. The acoustic signal is segmented via the attention system and speech labels are learned from a few repetitions of the label by the tutor. The attention system integrates bottom-up stimulus driven saliency calculation (delay-and-sum beamforming, a...

AbstractIn our previous work on ultralow-aspect ratio transonic turbine inlet guide vanes (IGVs) for a small turbofan engine (Hasenjäger et al., 2005, "Three Dimensional Aerodynamic Optimization for an Ultra-Low Aspect Ratio Transonic Turbine Stator Blade," ASME Paper No. GT2005-68680), we used numerical stochastic design optimization to propose the new design concept of an extremely aft-loaded airfoil to improve the difficult-to-control aerodynamic loss...
