Bayesian Inference for Big Data with Stochastic Gradient Markov Chain Monte Carlo
This EPSRC project involving Yee Whye Teh (Oxford), Arnaud Doucet (Oxford), and Christophe Andrieu (Bristol) aims to develop both methodologies and theoretical foundations for scalable Markov chain Monte Carlo methods for big data. The starting point was stochastic gradient Langevin dynamics (SGLD) (Welling and Teh 2011), where we have provided theoretical analyses in terms of both asymptotic convergence (Teh et al 2016) as well as weak error expansion (Vollmer et al 2016). We have also developed a range of novel scalable Monte Carlo algorithms based on different techniques.
