计算轮廓系数。1求簇内样本平均距离a(i)2求簇间样本平均距离b(i)3计算轮廓系数(b(i)-a(i))/max(a(i),b(i)).轮廓系数越大越好

Use both if possible: In practice, it’s often beneficial to use both methods together. Start with the elbow method to narrow down a reasonable range for the number of clusters, and then use the silhouette score to fine-tune the decision and validate the quality of the clustering.
