Dancing in the dark: galactic properties trace spin swings along the cosmic web
A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1. 2.

Faster independent component analysis by preconditioning with Hessian approximations
Independent Component Analysis (ICA) is a technique for unsupervised exploration of multi-channel data that is widely used in observational sciences.
Faster ICA under orthogonal constraint
Independent Component Analysis (ICA) is a technique for unsupervised exploration of multi-channel data widely used in observational sciences.
Stochastic algorithms with descent guarantees for ICA
We derive an online algorithm for the streaming setting, and an incremental algorithm for the finite sum setting, with the following benefits.
Accelerating likelihood optimization for ICA on real signals
We study optimization methods for solving the maximum likelihood formulation of independent component analysis (ICA).
Beyond Pham's algorithm for joint diagonalization
The approximate joint diagonalization of a set of matrices consists in finding a basis in which these matrices are as diagonal as possible.
Spectral independent component analysis with noise modeling for M/EEG source separation
Signals are modelled as a linear mixing of independent sources corrupted by additive noise, where sources and the noise are stationary Gaussian time series.
