OCPDet is a Python package for online changepoint detection, implementing state-of-the-art algorithms and a novel approach.

A Python package for online changepoint detection in univariate and multivariate data.

Algorithms implemented in ocpdet are

• CUSUM: Cumulative Sum algorithm, proposed by Page (1954)
• EWMA: Exponentially Weighted Moving Average algorithm, proposed by Roberts (1959)
• Two Sample tests: Nonparametric hypothesis testing for changepoint detection, proposed by Ross et al. (2011)
• Neural Networks: Novel approach based on sequentially learning neural networks, proposed by Hushchyn et al. (2020) and extended to online context (Master's Thesis)

Installation

pip install ocpdet
