Gamma-ray burst detection with Poisson-FOCuS and other trigger algorithms

Giuseppe Dilillo, Kes Ward, Idris A. Eckley +5

We describe how a novel online changepoint detection algorithm, called Poisson-FOCuS, can be used to optimally detect gamma-ray bursts within the computational constraints imposed…

Online Multivariate Changepoint Detection: Leveraging Links With Computational Geometry

Liudmila Pishchagina, Gaetano Romano, Paul Fearnhead +2

The increasing volume of data streams poses significant computational challenges for detecting changepoints online. Likelihood-based methods are effective, but a naive sequential i…

Simulation Based Composite Likelihood

Lorenzo Rimella, Chris Jewell, Paul Fearnhead

Inference for high-dimensional hidden Markov models is challenging due to the exponential-in-dimension computational cost of calculating the likelihood. To address this issue, we i…

A Constant-per-Iteration Likelihood Ratio Test for Online Changepoint Detection for Exponential Family Models

Kes Ward, Gaetano Romano, Idris Eckley +1

Online changepoint detection algorithms that are based on likelihood-ratio tests have been shown to have excellent statistical properties. However, a simple online implementation i…

Improving Power by Conditioning on Less in Post-selection Inference for Changepoints

Rachel Carrington, Paul Fearnhead

Post-selection inference has recently been proposed as a way of quantifying uncertainty about detected changepoints. The idea is to run a changepoint detection algorithm, and then…
