Abstract

The disadvantages of traditional classification algorithms are firstly discussed. Then, a new algorithm called HI-Rocchio is proposed. The HI-Rocchio algorithm includes two parts. The first part is an incremental Rocchio algorithm based on Rocchio algorithm, and the second is an improved Hierarchical clustering algorithm. The HI-Rocchio algorithm not only can generate new classes incrementally but also get multi hierarchical relationship between classes. Experiments verified the effectiveness of the algorithm.
