Experiments on three datasets show that the performance may be improved when we discard some labels which have few relevant instances. And we take different costs of query into account. The results are not consistent in three datasets. -
BatchRank: A Novel Batch Mode Active Learning Framework for Hierarchical Classification

In many applications, the set of class labels are organized in a hierarchical tree structure, with the leaf nodes as outputs and the internal nodes as clusters of outputs. This paper proposed a novel batch active selection criterion based on the label structure.
