Frontiers in Bayesian methods for computationally intractable models

点击翻译按钮获取中文摘要

This project aims to develop new statistical methods for the analysis of computationally intractable models. Direct statistical analyses are often impossible when models are highly complex or too large, or when the dataset is too big. Using simpler models means that the wrong questions are being answered. Using less data is wasteful of information. This project aims to develop new methods for Bayesian statistical inference when standard methods are intractable. By allowing otherwise unavailable analyses, such techniques can enable and accelerate across-the-board research advances. Key expected innovations are new bases for sampling from computationally intractable distributions and novel distributed computing algorithms which could be applied to problems in health economics to infectious disease modelling, from climate extremes to road traffic modelling.
