Default Re: How Many Iterations to Pick Best K-Cluster?

Different problem If you start with different initial centroids you get different results. If you run it enough you can materially change Ein and Eout because of a better centroid result.

By itself K-means clustering doesn't guarantee an optimal result although it reaches a stable result quickly (especially with so few data points).
