%description
A system designed for detecting concept drift in streaming datasets. It
offers a comprehensive suite of statistical methods to detect concept
drift, including methods for monitoring changes in data distributions over
time. The package supports several tests, such as Drift Detection Method
(DDM), Early Drift Detection Method (EDDM), Hoeffding Drift Detection
Methods (HDDM_A, HDDM_W), Kolmogorov-Smirnov test-based Windowing (KSWIN)
and Page Hinkley (PH) tests. The methods implemented in this package are
based on established research and have been demonstrated to be effective
in real-time data analysis. For more details on the methods, please check
