PCA-based branch and bound search algorithms for computing K nearest neighbors

Autor: Dirk Van Dyck, Xavier Rodet, Win D'haes

Publikováno v: Pattern recognition letters

In this paper, the efficiency of branch and bound search algorithms for the computation of K nearest neighbors is studied. The most important aspects that influence the efficiency of the search algorithm are: (1) the decomposition method, (2) the eli

TRUMPET AND TRUMPET PLAYER: A HIGHLY NONLINEAR INTERACTION STUDIED IN THE FRAMEWORK OF NONLINEAR DYNAMICS

Autor: Xavier Rodet, Christophe Vergez

Publikováno v: International Journal of Bifurcation and Chaos. 11:1801-1814

For musical purposes, a real-time physical model of trumpet-like instruments was built. The model exhibits different behaviors which are studied in the framework of nonlinear dynamical systems. Periodic, quasi-periodic, chaotic and intermittency regi

Automatic Characterisation of Musical Signals: Feature Extraction and Temporal Segmentation

Autor: Xavier Rodet, Jean-Luc Collette, Stéphane Rossignol, J. Soumagne, Philippe Depalle

Publikováno v: Journal of New Music Research. 28:281-295

This paper presents some results on automatic characterisation of musical and acoustic signals in terms of features attributed to signal segments. These features describe some of the musical and acoustical content of the sound and can be used in appl

Nonlinear Dynamics in Physical Models: Simple Feedback-Loop Systems and Properties

Autor: Xavier Rodet, Christophe Vergez

Publikováno v: Computer Music Journal. 23:18-34

This work establishes a new approach to the functioning of musical instruments that is oriented toward sound synthesis by computer, and its application to musical creation and composition. In this work, we only consider musical instruments that produ

A source-filter model for musical instrument sound transformation

Autor: Xavier Rodet, Marcelo Caetano

Publikováno v: ICASSP

The model used to represent musical instrument sounds plays a crucial role in the quality of sound transformations. Ideally, the representation should be compact and accurate, while its parameters should give flexibility to independently manipulate p
