%description
In streaming data analysis, it is crucial to detect significant shifts in
the data distribution or the accuracy of predictive models over time, a
phenomenon known as concept drift. The package aims to identify when
concept drift occurs and provide methodologies for adapting models in
non-stationary environments. It offers a range of state-of-the-art
techniques for detecting concept drift and maintaining model performance.
Additionally, the package provides tools for adapting models in response
to these changes, ensuring continuous and accurate predictions in dynamic
contexts. Methods for concept drift detection are described in Tavares
(2022) <doi:10.1007/s12530-021-09415-z>.
