ABSTRACT

There has been an intense development on the estimation of a sparse regression/classification model in statistics, machine learning and related fields. In this talk, we focus on the Bayesian approach to this problem, where sparsity is incorporated by the so-called spike-and-slab prior on the coefficients. Instead of replying on MCMC for posterior inference, we have developed scalable algorithms that approximate the posterior distribution and can process data batch by batch without loading all the data into memory. Asymptotic analysis of our approach, as well as empirical evaluation, will be presented.
