%description
By analyzing streaming datasets, it is possible to observe significant
changes in the data distribution or models' accuracy during their
prediction (concept drift). The goal of 'heimdall' is to measure when
concept drift occurs. The package makes available several state-of-the-art
methods. It also tackles how to adapt models in a nonstationary context.
Some concept drifts methods are described in Tavares (2022)
<doi:10.1007/s12530-021-09415-z>.
