Detection of Multiple Change–Points in Multivariate Time Series

We consider the multiple change–point problem for multivariate time series, including strongly dependent processes, with an unknown number of change–points. We assume that the covariance structure of the series changes abruptly at some unknown common change–point times. The proposed adaptive method is able to detect changes in multivariate i.i.d., weakly and strongly dependent series. This adap...

Dynamic detection of change points in long time series

We consider the problem of detecting change points (structural changes) in long sequences of data, whether in a sequential fashion or not, and without assuming prior knowledge of the number of these change points. We reformulate this problem as the Bayesian filtering and smoothing of a non standard state space model. Towards this goal, we build a hybrid algorithm that relies on particle filteri...

Multi-Scale Change Point Detection in Multivariate Time Series

A core problem in time series data is learning when things change. This problem is especially challenging when changes appear gradually and at varying timescales, such as in health. Convolutional Neural Networks (CNNs) have the potential to recognize and localize complex patterns, but are sensitive to scale. We propose a new class of scale and shift invariant neural networks that augment CNNs w...

Bayesian approach to change points detection in time series

Change points detection in time series is an important area of research in statistics, has a long history and has many applications. However, very often change point analysis is only focused on the changes in the mean value of some quantity in a process. In this work we consider time series with discrete point changes which may contain a finite number of changes of probability density functions...

Testing for Change Points in Time Series

This article considers the CUSUM-based (cumulative sum) test for a change point in a time series. In the case of testing for a mean shift, the traditional Kolmogorov–Smirnov test statistic involves a consistent long-run variance estimator, which is needed to make the limiting null distribution free of nuisance parameters. The commonly used lag-window type long-run variance estimator requires to...
