Bayesian inference is a pretty classical problem in statistics and machine learning that relies on the well known Bayes theorem and whose main drawback lies, most of the time, in some very heavy computations; Markov Chain Monte Carlo (MCMC) methods are aimed at simulating samples from densities that can be very complex and/or defined up to a factor. • Describe the Bayesian inference • Summarize bayesian inference and mcmc mcmc-bayes.pdf the MCMC methods • Present a briefly introduction to INLA • Ilustrate the software available to implement INLA (r-INLA package) • Provide some references to more details about INLA • Concluding remarks 3 of 36. Even when we have written a sensible probabilistic model, the results can be misleading due to the inference algorithm, whether because the algorithm has failed or because we have chosen an inappropriate algorithm.
