Social Network Big Data Hierarchical High-Quality Node Mining
Input: the dataset with samples and the number of clusters . | Output: clusters and minimizes the squared error criterion. | Steps. | (1) Arbitrarily select samples as initial cluster centers | (2) Repeat the above steps | (3) Calculate the mean of the samples in the cluster and reassign the values of the samples to the most similar cluster | (4) Updating the cluster means, i.e., calculating the mean of the samples in each cluster | (5) Until no more changes occur |
