Summary

This work proposes a new active learning method for evolving data streams based on a combination of density and prediction uncertainty (DBALSTREAM), which allows focusing labelling efforts in the instance space where more data is concentrated; hence the benefits of learning a more accurate classifier are expected to be higher.
