Improved Disease Outbreak Detection from Out-of-sequence measurements Using Markov-switching Fixed-lag Particle Filters

Conor Rosato, Joshua Murphy, Siân E. Jenkins +7

Particle filters (PFs) have become an essential tool for disease surveillance, as they can estimate hidden epidemic states in nonlinear and non-Gaussian models. In epidemic modelli…

An $O (lo g_{2} N)$ SMC $^{2}$ Algorithm on Distributed Memory with an Approx. Optimal L-Kernel

Conor Rosato, Alessandro Varsi, Joshua Murphy +1

Calibrating statistical models using Bayesian inference often requires both accurate and timely estimates of parameters of interest. Particle Markov Chain Monte Carlo (p-MCMC) and…
