EN Three block based ensembles, AWE, BWE and ACE, are considered in the perspective of learning from data streams with concept drift. AWE updates the ensemble after processing each successive block of incoming examples, while the other ensembles are additionally extended by different drift detectors. Experiments show that these extensions improve classification accuracy, in particular for sudden changes occurring within the block, as well as reduce computational costs.
