A Survey of Monte Carlo Methods for Parameter Estimation

no code implementations25 Jul 2021 D. Luengo, L. Martino, M. Bugallo, V. Elvira, S. Särkkä

MC methods proceed by drawing random samples, either from the desired distribution or from a simpler one, and using them to compute consistent estimators.

MCMC-driven importance samplers

no code implementations6 May 2021 F. Llorente, E. Curbelo, L. Martino, V. Elvira, D. Delgado

Monte Carlo sampling methods are the standard procedure for approximating complicated integrals of multidimensional posterior distributions in Bayesian inference.

Adaptive quadrature schemes for Bayesian inference via active learning

no code implementations31 May 2020 F. Llorente, L. Martino, V. Elvira, D. Delgado, J. López-Santiago

For the Gaussian case, we also provide a novel procedure for fitting the bandwidth parameter, in order to build a suitable emulator of a density function.

Group Importance Sampling for Particle Filtering and MCMC

no code implementations10 Apr 2017 L. Martino, V. Elvira, G. Camps-Valls

Importance Sampling (IS) is a well-known Monte Carlo technique that approximates integrals involving a posterior distribution by means of weighted samples.
