A State-Space Perspective on Modelling and Inference for Online Skill Rating

1 code implementation4 Aug 2023 Samuel Duffield, Samuel Power, Lorenzo Rimella

We summarise popular methods used for skill rating in competitive sports, along with their inferential paradigms and introduce new approaches based on sequential Monte Carlo and discrete hidden Markov models.

Consistent and fast inference in compartmental models of epidemics using Poisson Approximate Likelihoods

1 code implementation26 May 2022 Michael Whitehouse, Nick Whiteley, Lorenzo Rimella

In contrast to the popular ODE approach to compartmental modelling, in which a large population limit is used to motivate a deterministic model, PALs are derived from approximate filtering equations for finite-population, stochastic compartmental models, and the large population limit drives consistency of maximum PAL estimators.

Inference in Stochastic Epidemic Models via Multinomial Approximations

1 code implementation24 Jun 2020 Nick Whiteley, Lorenzo Rimella

We introduce a new method for inference in stochastic epidemic models which uses recursive multinomial approximations to integrate over unobserved variables and thus circumvent likelihood intractability.

Dynamic Bayesian Neural Networks
