Solare Variabilität und Klimaschwankungen auf einer Zeitskala von einigen Dekaden bis Jahrhunderten im Holozän
… Des weiteren wurde an D14C mit Hilfe mehrerer Methoden (Singuläre Spektrum Analyse, Multi-Taper Methode, Maximum Entropie Methode, digitale Bandpassfilterung (IIR) und Wavelets) Spektralanalysen durchgeführt, deren Schwerpunkt auf Frequenzen lag, welche der variablen Sonne zugeordnet werden. Es …

Diskriminative Modellkombination in Spracherkennungssystemen mit großem Wortschatz
In this work, the theory of Discriminative Model Combination, DMC, is developed and implemented for large vocabulary continuous speech recognition. DMC is based on a discriminative training of the free parameters of distributions belonging to the exponential family. It is independent of the …

Simulating quantum systems on classical computers with matrix product states
In this thesis, the numerical simulation of strongly-interacting many-body quantum-mechanical systems using matrix product states (MPS) is considered. Compared to classical systems, quantum many-body systems possess an exponentially enlarged number of degrees of freedom, significantly complicating …

Statistical methods in natural language understanding and spoken dialogue systems
… The second model is a direct model based on the maximum entropy framework and works similar to a tagger. For the direct model, we define several feature functions that capture dependencies between words and concepts. Both methods have the advantage that only source-target pairs in the form of …

A log-linear discriminative modeling framework for speech recognition
… the optimization of log-linear models with the maximum mutual information (MMI) criterion. This thesis suggests an extension of GIS to log-linear models including hidden variables, and to other training criteria (e.g. MPE). Finally, investigations on convex optimization in speech recognition are …
