Deep Horseshoe Gaussian Processes

no code implementations4 Mar 2024 Ismaël Castillo, Thibault Randrianarisoa

Deep Gaussian processes have recently been proposed as natural objects to fit, similarly to deep neural networks, possibly complex features present in modern data samples, such as compositional structures.

Semiparametric inference using fractional posteriors

no code implementations19 Jan 2023 Alice L'Huillier, Luke Travis, Ismaël Castillo, Kolyan Ray

We establish a general Bernstein--von Mises theorem for approximately linear semiparametric functionals of fractional posterior distributions based on nonparametric priors.

no code implementations12 Jan 2021 Sayantan Banerjee, Ismaël Castillo, Subhashis Ghosal

Bayesian methods have been proposed for such problems more recently, where the prior takes care of the sparsity structure.
