For scientific applications involving large and complex data, it is useful to develop probability models and inference methods but issues arise in terms of computing speed and stability. In such settings accurate uncertainty quantification is critical and common fast approximations often do a poor job of UQ. In this talk, I discuss recent developments in scaling up sampling algorithms to big problems - considering broad classes of approximate and parallelizable MCMC algorithms with corresponding theory guarantees. A particular focus will be on data augmentation approaches. A variety of applications will be provided as motivation.
