WebOct 6, 2024 · Initially, the popular “elbow method” was used to identify the optimal number of clusters. This method relied on plotting the within-sum-of-squares (WSS) values for a range of k’s and choosing a k-value where the WSS began to level off, resulting in an optimal k-value of 16 ( S2 Fig ). WebSep 8, 2024 · One of the most common ways to choose a value for K is known as the elbow method, which involves creating a plot with the number of clusters on the x-axis and the total within sum of squares on the y-axis and then identifying where an “elbow” or bend appears in the plot. The point on the x-axis where the “elbow” occurs tells us the ...
