Approximate Bayesian Computation and Simulation-Based Inference for Complex Stochastic Epidemic Models

摘要

Approximate Bayesian Computation (ABC) and other simulation-based inference methods are becoming increasingly used for inference in complex systems, due to their relative ease-of-implementation. We briefly review some of the more popular variants of ABC and their application in epidemiology, before using a real-world model of HIV transmission to illustrate some of challenges when applying ABC methods to high-dimensional, computationally intensive models. We then discuss an alternative approach— history matching—that aims to address some of these issues, and conclude with a comparison between these different methodologies.
