Elbow curve and Silhouette plots both are very useful techniques for finding the optimal K for k-means clustering. In real-world data sets, you will find quite a lot of cases where the elbow curve is not sufficient to find the right ‘K’. In such cases, you should use the silhouette ...

The elbow, or “knee of a curve”, approach is the most common and simplest means of determining the appropriate cluster number prior to running clustering algorithms, suc has the K-means algorithm. The elbow method entails running the clustering algorithm (often the K-means algorithm) on the...
