State Change Detection Using Multivariate Synchronization Measure from Physiological Signals

Martin Hasler, Cristian Carmeli, Kumiko Oshima

The cardiovascular system can be macro-modelled as a collection of coupled oscillators. Recently, the use of mutual couplings of these oscillators to characterize the state of the system during anaesthesia has been proposed. Assuming that the synchronizati ...

Discrmininant Models for Text-independent Speaker Verification

This thesis addresses text-independent speaker verification from a machine learning point of view. We use the machine learning framework to better define the problem and to develop new unbiased performance measures and statistical tests to compare objectiv ...

SURE-Based Wavelet Thresholding Integrating Inter-Scale Dependencies

Michaël Unser, Thierry Blu, Florian Luisier

We propose here a new pointwise wavelet thresholding function that incorporates inter-scale dependencies. This non-linear function depends on a set of four linear parameters per subband which are set by minimizing Stein's unbiased MSE estimate (SURE). Our ...

Data-driven controller tuning using the correlation approach

Ljubisa Miskovic

The essential ingredients of control design procedures include the acquisition of process knowledge and its efficient integration into the controller. In many practical control applications, a reliable mathematical description of the plant is difficult or ...

Anisotropic Gaussian Filters for Face Class Modeling

Jean-Philippe Thiran, Vlad Popovici, Julien Meynet

In this paper we propose a new approach to automatic human face detection which employs anisotropic Gaussian filters as local image descriptors. We then show how the paradigm of classifier combination can be used for building a face detector that outperfor ...

Constrained Tracking on a Road Network

Matthias Grossglauser

Many applications of wireless ad hoc sensor and actuator networks (WSANs) rely on the knowledge of node locations. These are challenging to obtain when nodes are mobile and are not equipped with any expensive positioning hardware. In this paper, we are int ...

A Maximum-Likelihood Formalism for Sub-Resolution Axial Localization of Fluorescent Nanoparticles

Michaël Unser, Dimitri Nestor Alice Van De Ville, François Aguet

One of the ongoing challenges in single particle fluorescence microscopy resides in estimating the axial position of particles with sub-resolution precision. Due to the complexity of the diffraction patterns generated by such particles, the standard fittin ...

Path integral evaluation of the kinetic isotope effects based on the quantum instanton approximation

Jiri Vanicek

A general method for computing kinetic isotope effects is described. The method uses the quantum-instanton approxn. and is based on the thermodn. integration with respect to the mass of the isotopes and on the path-integral Monte- A general method for comp ...

How Do Correlation and Variance of Base-Experts Affect Fusion in Biometric Authentication Tasks?

Samy Bengio, Norman Hoon Thian Poh

Combining multiple information sources such as subbands, streams (with different features) and multi modal data has shown to be a very promising trend, both in experiments and to some extend in real-life biometric authentication applications. Despite consi ...
