Latent Stochastic Differential Equations for Change Point Detection
IEEE Access, 2023 Automated analysis of complex systems based on multiple readouts remains a challenge. Change point detection algorithms are aimed to locating abrupt changes in the time series behaviour of a process.

Network representations of attractors for change point detection
Communications Physics, 2023 A common approach to monitoring the status of physical and biological systems is through the regular measurement of various system parameters. Changes in a system’s underlying dynamics manifest as changes in the behaviour of the observed time series. For

On Matched Filtering for Statistical Change Point Detection
IEEE Open Journal of Signal Processing, 2020 Non-parametric and distribution-free two-sample tests have been the foundation of many change point detection algorithms. However, randomness in the test statistic as a function of time makes them susceptible to false positives and localization ambiguity.

Three Dimensional Change Detection Using Point Clouds: A Review
Geomatics, 2022 Change detection is an important step for the characterization of object dynamics at the earth’s surface. In multi-temporal point clouds, the main challenge is to detect true changes at different granularities in a scene subject to significant noise and ...

Study on a mother wavelet optimization framework based on change-point detection of hydrological time series [PDF]
Hydrology and Earth System Sciences, 2023 Hydrological time series (HTS) are the key basis of water conservancy project planning and construction. However, under the influence of climate change, human activities and other factors, the consistency of HTS has been destroyed and cannot meet the ...

Online change-point detection with kernels
Pattern Recognition, 2023 Change-points in time series data are usually defined as the time instants at which changes in their properties occur. Detecting change-points is critical in a number of applications as diverse as detecting credit card and insurance frauds, or intrusions into networks. Recently the authors introduced an online kernel-based change-point detection method

Hierarchical Spatio-Temporal Change-Point Detection
The American Statistician, 2023 Detecting change-points in multivariate settings is usually carried out by analyzing all marginals either independently, via univariate methods, or jointly, through multivariate approaches. The former discards any inherent dependencies between different marginals and the latter may suffer from domination/masking among different change-points of ...
