A copula-based model of speculative price dynamics in discrete time
This paper suggests a new technique to construct first order Markov processes using products of copula functions, in the spirit of Darsow et al. (1992). The approach requires the...

On the Fourier Extension of Nonperiodic Functions
We obtain exponentially accurate Fourier series for nonperiodic functions on the interval [-1, 1] by extending these functions to periodic functions on a larger domain. The series ...

Dynamic signal combining for distributed microphone systems in car environments
Distributed microphone systems in cars usually provide dedicated microphones for several speakers where each microphone captures the desired speech signal at the best. The signal ...

Time-frequency reassigned features for automatic chord recognition
This paper addresses feature extraction for automatic chord recognition systems. Most chord recognition systems use chroma features as a front-end and some kind of classifier (HM...

Automatic speech recognition using Hidden Conditional Neural Fields
Hidden Conditional Random Fields(HCRF) is a very promising approach to model speech. However, because HCRF computes the score of a hypothesis by summing up linearly weighted featu...
