Functional Data Analysis By Matrix Completion1
Victor Panaretos, Marie-Hélène Descary
Functional data analyses typically proceed by smoothing, followed by functional PCA. This paradigm implicitly assumes that rough variation is due to nuisance noise. Nevertheless, relevant functional features such as time-localised or short scale fluctuatio ...
INST MATHEMATICAL STATISTICS2019Self-consistent model for the saturation mechanism of the response to harmonic forcing in the backward-facing step flow
François Gallaire, Vladislav Mantic Lugo
Certain flows denominated as amplifiers arc characterized by their global linear stability while showing large linear amplifications to sustained perturbations. As the forcing amplitude increases, a strong saturation of the response appears when compared t ...
Cambridge University Press2016A simple continuous excitation model for parametric vocoding
Philip Neil Garner, Milos Cernak
We describe a continuous-pitch parametric vocoder suitable for speech coding and statistical text to speech synthesis. The spectral model is based on linear prediction. We show that glottal modelling techniques from recent literature can be cherry-picked t ...
Idiap2015Joint Source-Filter Optimization for Accurate Vocal Tract Estimation Using Differential Evolution
Jean-Marc Vesin, Olaf Schleusing
In this work, we present a joint source-filter optimization approach for separating voiced speech into vocal tract (VT) and voice source components. The presented method is pitch-synchronous and thereby exhibits a high robustness against vocal jitter, shim ...
Ieee-Inst Electrical Electronics Engineers Inc2013Understanding the effect of side groups in ionic liquids on carbon-capture properties: a combined experimental and theoretical effort
Ionic liquids are an emerging class of materials with applications in a variety of fields. Steady progress has been made in the creation of ionic liquids tailored to specific applications. However, the understanding of the underlying structure-property rel ...

Ecole Polytechnique Fédérale de Lausanne2011Autoregressive Models of Amplitude Modulations in Audio Compression
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy
We present a scalable medium bit-rate wide-band audio coding technique based on frequency domain linear prediction (FDLP). FDLP is an efficient method for representing the long-term amplitude modulations of speech/audio signals using autoregressive models. ...

Idiap2009Autoregressive Modelling of Hilbert Envelopes for Wide-band Audio Coding
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy
Frequency Domain Linear Prediction (FDLP) represents the technique for approximating temporal envelopes of a signal using autoregressive models. In this paper, we propose a wide-band audio coding system exploiting FDLP. Specifically, FDLP is applied on cri ...
