An encoding approach for stable change point detection

open access: yesMachine Learning
AbstractWithout imposing prior distributional knowledge underlying multivariate time series of interest, we propose a nonparametric change-point detection approach to estimate the number of change points and their locations along the temporal axis.

Bootstrap for change point detection

open access: yes, 2017
In Change point detection task Likelihood Ratio Test (LRT) is sequentially applied in a sliding window procedure. Its high values indicate changes of parametric distribution in the data sequence. Correspondingly LRT values require predefined bound for their maximum.

Marginal Likelihood for Markov-Switching and Change-Point Garch Models [PDF]

open access: yes
GARCH volatility models with fixed parameters are too restrictive for long time series due to breaks in the volatility process. Flexible alternatives are Markov-switching GARCH and change-point GARCH models. They require estimation by MCMC methods due to

Temporal convolutional networks work as general feature extractors for single-particle diffusion analysis

open access: yesJPhys Photonics
The application of deep learning (DL) approaches to the study of particle diffusion is becoming increasingly widespread, achieving highly accurate predictive performance that is often challenging to attain with traditional analytical tools.

Label Free Change Detection on Streaming Data with Cooperative Multi-objective Genetic Programming

open access: yes, 2013
Classification under streaming data conditions requires that the machine learning approach operate interactively with the stream content. Thus, given some initial machine learning classification capability, it is not possible to assume that the process ...

Variance changes detection in multivariate time series [PDF]

open access: yes, 2004
This paper studies the detection of step changes in the variances and in the correlation structure of the components of a vector of time series. Two procedures are considered.
