MALA – Metropolis Adjusted Langevin Algorithm in Julia

MALA – Metropolis Adjusted Langevin Algorithm in Julia

Metropolis Adjusted Langevin Algorithm (MALA) Haven’t dumped much code here in a while. Here’s a Julia implementation of MALA with an arbitrary preconditioning matrix M. Potentially I might use this in the future. Generic Julia Implementation Arguments are a function to evaluate the logdensity, function to evaluate the gradient, a step size h, a preconditioning […] The post MALA – Metropolis Adjusted Langevin Algorithm in Julia appeared first on I've…
