Based on this estimator, we propose a Bayesian change point detection method, which is one of the fastest Bayesian methodologies. We demonstrate through empirical work the good performance of our approach vis-a-vis some state-of-the-art benchmarks. Interestingly, despite having a Gaussian noise ...

Changepoints are abrupt variations in the generative parameters of a data sequence. Online detection of changepoints is useful in modelling and prediction of time series in application areas such as finance, biometrics, and robotics. While frequentist me
Adams and MacKay's 2007 paper, "Bayesian Online Changepoint Detection", introduces a modular Bayesian framework for online estimation of changes in the generative parameters of sequential data. I discuss this paper in detail. Published 13 August 2019Introduction Given sequential data such as stock ...
BEAST: A Bayesian Ensemble Algorithm for Change-Point Detection and Time Series Decomposition BEAST (Bayesian Estimator of Abrupt change, Seasonality, and Trend) is a fast, generic Bayesian model averaging algorithm to decompose time series or 1D sequential data into individual components, such as abr...
3.1. Bayesian online change-point detection BOCPD, introduced by [3], is a CPD method that exhibits a number of advantages. First, regime detection occurs online and, as such, BOCPD is suitable for real-time applications. Moreover, the number of regimes is not set a priori, but CP defi...
