Project description

Classifier based non-parametric change point detection

Change point detection tries to identify times when the probability distribution of a stochastic process or time series changes. Existing methods either assume a parametric model for within-segment distributions or a based on ranks or distances, and thus fail in scenarios with reasonably large dimensionality.

changeforest implements a classifier based algorithm that consistently estimates change points without any parametric assumptions even in high-dimensional scenarios. See [1] for details.
