Abstract: A three-stage framework and a simple implemented algorithm for clustering mixed data are proposed. In the framework, the mixed dataset is divided into several subsets according to the different types of attributes, and each subset is clustered using according off-the-shelf algorithms, the results are combined as a new categorical dataset and then be clustered. The final result is the answer for clustering the original mixed dataset. The experimental results show that the proposed framework and the implemented algorithm can be used to cluster the mixed dataset efficiently and it is prior to the k-prototypes.
