In this way, the Arrears department can only treat defaulters intensively, who really have payment problems. Dat ...

Mining Concept-Drifting Data Streams using Ensemble Classifiers
... Incremental or online data mining methods [29, 15] are another option for mining data streams. These methods continuously revise and refine a model by incorporating new data as they arrive. However, in order to guarantee that the model trained incrementally is identical to the model trained in the b ...
