High-dimensional Gaussian sampling: a review and a unifying approach based on a stochastic proximal point algorithm
Maxime Vono, Nicolas Dobigeon, Pierre Chainais
Efficient sampling from a high-dimensional Gaussian distribution is an old but high-stake issue. Vanilla Cholesky samplers imply a computational cost and memory requirements which…
Quantitative inference of the column densities from 3 mm molecular emission: A case study towards Orion B
Pierre Gratier, Jérôme Pety, Emeric Bron +21
Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or…
Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids
Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21
The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…
Kernel interpolation with continuous volume sampling
Ayoub Belhadji, Rémi Bardenet, Pierre Chainais
A fundamental task in kernel methods is to pick nodes and weights, so as to approximate a given function from an RKHS by the weighted sum of kernel translates located at the nodes.…
