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…
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…
gfpop: an R Package for Univariate Graph-Constrained Change-Point Detection
Vincent Runge, Toby Dylan Hocking, Gaetano Romano +3
In a world with data that change rapidly and abruptly, it is important to detect those changes accurately. In this paper we describe an R package implementing a generalized version…
