National audienceBayesian posterior distributions can be numerically intractable, even by the means of Markov Chains Monte Carlo methods. Bayesian variational methods can then be used to compute directly (and fast) a deterministic approximation of these posterior distributions. This paper describes the principle of variational methods and their applications in the Bayesian inference, surveys the main theoretical results and details two examples in the neuroimage field.En estimation bayésienne, les lois a posteriori sont rarement accessibles, même par des méthodes de Monte-Carlo par Chaîne de Markov. Les méthodes bayésiennes variationnelles permettent de calculer directement (et rapidement) une approximation déterministe des lois a posterior...
