Adaptive K-means Algorithm with Dynamically Changing Cluster Centers and K-Value
In allusion to the disadvantage of having to obtain the number of clusters in advance and the sensitivity to selecting initial clustering centers in the K-means algorithm,an improved K-means algorithm is proposed,that the cluster centers and the number of clusters are dynamically changing.The new algorithm determines the cluster centers by calculating the density of data points and shared nearest neighbor similarity,and controls the clustering categories by using the average shared nearest neighbor self-similarity.The experimental results of IRIS testing data set show that the algorithm can select the cluster cennters and can distinguish between different types of cluster efficiently.
