讲座摘要：

       Motivated by the goal of improving the efficiency of a sequential design with small sample size, we propose a novel Bayesian stochastic approximation method to estimate the root of a regression function. The method features adaptive local modelling and nonrecursive iteration. Consistency of the Bayes estimator and coherence property of the design are obtained. Simulation studies show its superiority in small-sample performance to Robbins-Monro type procedures. Extension to a version of generalized multivariate quantile is presented.
