%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 **heimdall** 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, **heimdall** 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>.
