The Zig-Zag process & Super-efficient Sampling For Bayesian Analysis Of Big Data

Standard MCMC methods can scale poorly to big data settings due to the need to evaluate the likelihood at each iteration. There have been a number of approximate MCMC algorithms that use sub-sampling

Density Estimation: Views From Machine Learning And Statistics

Machine learning methods are getting rapidly better at fantasizing novel complex objects, such as images or audio, based on large training sets of examples. Some of the methods behind these impressive demonstrations are also useful for scientific data analysis in two ways. First, the probabilistic…
