Abstract
The invention relates to a method for determining a time for retraining a data mining model, comprising the steps of: calculating multivariate statistics of a training model during a training phase; storing the multivariate statistics in the data mining model; monitoring at least one distribution parameter of application data as a function of time during a deployment phase; and evaluating reliability of the data mining model based on the multivariate statistics and at least one distribution parameter.
