WebSep 28, 2024 · We'll resort to the K-means algorithm to do the job for us, but in this example, we'll be manually performing the algorithm. Usually, the algorithm is enacted using programming tools like Python and R. For the sake of simplifying our example, we'll agree on 2 as the number of our clusters. That means that K=2.
