WebAug 31, 2024 · In practice, we use the following steps to perform K-means clustering: 1. Choose a value for K. First, we must decide how many clusters we’d like to identify in the data. Often we have to simply test several different values for K and analyze the results to see which number of clusters seems to make the most sense for a given problem.
