Selection of Clustering Algorithms based on a Validity Index

It is the precondition and guarantee for high clustering quality that are to select a proper clustering algorithm for a given dataset.The algorithm selection method based on a validity index is proposed.In this method,a proper algorithm is selected for a dataset through the quality evaluation of clustering results from different clustering algorithms.The proposed method has the advantage of guaranteeing clustering quality when there is less prior knowledge about the dataset.The experimental results show that the proposed method is effective and correctly finds out the proper clustering algorithm suiting for the experimental dataset.
