Two-way kernel matrix puncturing: towards resource-efficient PCA and spectral clustering
Romain Couillet, Florent Chatelain, Nicolas Le Bihan
The article introduces an elementary cost and storage reduction method for spectral clustering and principal component analysis. The method consists in randomly "puncturing" both t…
Asymptotic regime for impropriety tests of complex random vectors
Florent Chatelain, Nicolas Le Bihan, Jonathan H. Manton
Impropriety testing for complex-valued vector has been considered lately due to potential applications ranging from digital communications to complex media imaging. This paper prov…
Robust control of varying weak hyperspectral target detection with sparse non-negative representation
Raphael Bacher, Celine Meillier, Florent Chatelain +1
In this study, a multiple-comparison approach is developed for detecting faint hyperspectral sources. The detection method relies on a sparse and non-negative representation on a h…
Isotropic Multiple Scattering Processes on Hyperspheres
Nicolas Le Bihan, Florent Chatelain, Jonathan H. Manton
This paper presents several results about isotropic random walks and multiple scattering processes on hyperspheres . It allows one to derive the Fourier expansio…
Bayesian Model for Multiple Change-points Detection in Multivariate Time Series
Flore Harlé, Florent Chatelain, Cédric Gouy-Pailler +1
This paper addresses the issue of detecting change-points in multivariate time series. The proposed approach differs from existing counterparts by making only weak assumptions on b…
