Continuous stochastic approximation procedure for evaluating the point at which the regression function stops to be non-positive
Convergence presque sûre et en moyenne des processus d'approximation stochastique, (1ère Partie) processus de Dvoretzky
Coupling a stochastic approximation version of EM with an MCMC procedure
The stochastic approximation version of EM (SAEM) proposed by Delyon et al. (1999) is a powerful alternative to EM when the E-step is intractable. Convergence of SAEM toward a maximum of the observed likelihood is established when the unobserved data are simulated at each iteration under the conditional distribution. We show that this very restrictive assumption can be weakened. Indeed, the results of Benveniste et al. for stochastic approximation with markovian perturbations are used to establish...
