An Efficient Chernoff Faces Clustering Algorithms
Chernoff faces are an excellent tool in the visualization of multivariate data. It is drawn by assigning the data dimension to the facial feature. Each face is human like and the user identifies the clusters from the faces. To improve the shortcomings of Chernoff faces clustering, we present a simple and efficient implementation of Chernoff faces with the integration of principle component analysis(PCA) and k-means algorithm. The two-stage procedure-first using k-means algorithm to produce the cluster prototypes that are then used to reclassify all data or the partial special data using the improved Chernoff faces based on PCA-is found to reduce the subjective judgment time of classify data and to perform well when compared with Chernoff faces clustering.
