Implementation Of K-means Method, Elbow Method, Silhouette Analysis

This article describes how the k-means method works and how it is implemented. In addition, the k-means method requires that the number of clusters to be classified be given in advance, and the elbow method and silhouette analysis are introduced as methods for determining the optimal number of clusters.
