Bayesian nonparametric Principal Component Analysis
Clément Elvira, Pierre Chainais, Nicolas Dobigeon
Principal component analysis (PCA) is very popular to perform dimension reduction. The selection of the number of significant components is essential but often based on some practi…
On the zeros of the spectrogram of white noise
Rémi Bardenet, Julien Flamant, Pierre Chainais
In a recent paper, Flandrin [2015] has proposed filtering based on the zeros of a spectrogram, using the short-time Fourier transform and a Gaussian window. His results are based o…
Spectral analysis of stationary random bivariate signals
Julien Flamant, Nicolas Le Bihan, Pierre Chainais
A novel approach towards the spectral analysis of stationary random bivariate signals is proposed. Using the Quaternion Fourier Transform, we introduce a quaternion-valued spectral…
