Error performances of a model-based biplane fluoroscopic system for tracking knee prosthesis during treadmill gait task

Roentgen stereophotogrammetry analysis technique allows an accurate measurement of knee joint prosthesis position and orientation using two X-ray images. Although this technique is used generally during static procedure, it is possible to use it with a bip ...

Decoding the Population Activity of Grid Cells for Spatial Localization and Goal-Directed Navigation

Alexander Mathis

Mammalian grid cells fire whenever an animal crosses the points of an imaginary, hexagonal grid tessellating the environment. Here, we show how animals can localize themselves and navigate by reading-out a simple population vector of grid cell activity acr ...

Comparison of force-based and displacement-based design approaches for RC coupled walls in New Zealand

Katrin Beyer

Reinforced concrete coupled walls are a common lateral load resisting system used in multi-storey buildings. The effect of the coupling beams can improve seismic performance, but at the same time adds complexity to the design procedure. A case study couple ...

Improved overlap speech diarization of meeting recordings using long-term conversational features

Hervé Bourlard, Sree Harsha Yella

Overlapping speech is a source of significant errors in speaker diarization of spontaneous meeting recordings. Recent works on speaker diarization have attempted to solve the problem of overlap detection using classifiers trained on acoustic and spatial fe ...

Advances in Fast Multistream Diarization based on the Information Bottleneck Framework

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

Multistream diarization is an effective way to improve the diarization performance, MFCC and Time Delay Of Arrivals (TDOA) being the most commonly used features. This paper extends our previous work on information bottleneck diarization aiming to include l ...

Multistream Speaker Diarization beyond Two Acoustic Feature Streams

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

Speaker diarization for meetings data are recently converging towards multistream systems. The most common complementary features used in combination with MFCC are Time Delay of Arrival (TDOA). Also other features have been proposed although, there are no ...

Mutual Information based Channel Selection for Speaker Diarization of Meetings Data

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

In the meeting case scenario, audio is often recorded using Multiple Distance Microphones (MDM) in a non-intrusive manner. Typically a beamforming is performed in order to obtain a single enhanced signal out of the multiple channels. This paper investigate ...

Analysing the temporal dynamics of model performance for hydrological models

Bettina Schaefli

The temporal dynamics of hydrological model performance gives insights into errors that cannot be obtained from global performance measures assigning a single number to the fit of a simulated time series to an observed reference series. These errors can in ...

Integration of TDOA Features in Information Bottleneck Framework for Fast Speaker Diarization

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

In this paper we address the combination of multiple feature streams in a fast speaker diarization system for meeting recordings. Whenever Multiple Distant Microphones (MDM) are used, it is possible to estimate the Time Delay of Arrival (TDOA) for differen ...
