Sequential detection of a temporary change in multivariate time series

چکیده

In this work, we aim to provide a new and efficient recursive detection method for temporarily monitored signals. Motivated by the case of propagation an event over field sensors, assumed that change in statistical properties signals can only be temporary. Unfortunately, our best knowledge, existing simple techniques such as ones based on cumulative sum (CUSUM) do not consider temporary aspect multivariate time series. paper, propose novel sequential algorithm, named Temporary-Event-CUSUM (TE-CUSUM). By combining with adaptive way aggregate local CUSUM variables from each data stream, empirically show TE-CUSUM has very good rate passing through sensors noisy environment.

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...

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...

Contextual Time Series Change Detection

Time series data are common in a variety of fields ranging from economics to medicine and manufacturing. As a result, time series analysis and modeling has become an active research area in statistics and data mining. In this paper, we focus on a type of change we call contextual time series change (CTC) and propose a novel two-stage algorithm to address it. In contrast to traditional change de...

Change Detection in Markov-modulated Time Series

In this paper, we address the problem of online change detection of Markov-modulated time series models. For simplicity, we look at Auto-regressive time-series models the parameters of which are modulated by a nite-state homogeneous Markov chain. We propose a Cumulative Sum based statistical test to detect abrupt changes is such processes. Computation of average run length functions, in particu...
