focus and focus-cpt: Fast Online Changepoint Detection in R and Python
Gaetano Romano, Kes Ward, Yuntang Fan +4
We present an R and Python package for fast online changepoint detection in univariate and multivariate data streams for a variety of models. The package implements the focus famil…
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…
Searching for long faint astronomical high energy transients: a data driven approach
Riccardo Crupi, Giuseppe Dilillo, Kester Ward +3
HERMES (High Energy Rapid Modular Ensemble of Satellites) pathfinder is an in-orbit demonstration consisting of a constellation of six 3U nano-satellites hosting simple but innovat…
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…
Poisson-FOCuS: An efficient online method for detecting count bursts with application to gamma ray burst detection
Kes Ward, Giuseppe Dilillo, Idris Eckley +1
Gamma-ray bursts are flashes of light from distant exploding stars. Cube satellites that monitor photons across different energy bands are used to detect these bursts. There is a n…
