How to Determine the Optimal K for K-Means? Khyati Mahendru 5 min read · Jun 17, 2019 -- 12 Listen Share Press enter or click to view image in full size Introduction The K-Means algorithm needs no introduction. It is simple and perhaps the most commonly used algorithm for clustering. The basic idea behind k-means consists of defining k clusters such that total within-cluster variation (or error) is minimum . I encourage you to check out the below articles for an in-depth explanation of different methods of clustering before proceeding further: An Introduction to Clustering and different method
