Contrast-Free ICA and Causal Inference via Wasserstein Distances to the Gaussian
Félix Laplante, Christophe Ambroise, Pierre Humbert
We study the squared -Wasserstein distance to the standard Gaussian as a non-Gaussianity criterion and use it for linear Independent Component Analysis (ICA) and causal discover…
Learning the piece-wise constant graph structure of a varying Ising model
Batiste Le Bars, Pierre Humbert, Argyris Kalogeratos +1
This work focuses on the estimation of multiple change-points in a time-varying Ising model that evolves piece-wise constantly. The aim is to identify both the moments at which sig…
Multivariate Convolutional Sparse Coding with Low Rank Tensor
Pierre Humbert, Julien Audiffren, Laurent Oudre +1
This paper introduces a new multivariate convolutional sparse coding based on tensor algebra with a general model enforcing both element-wise sparsity and low-rankness of the activ…
