"WebJun 6, 2024 · The goal of k-means is to minimize the distance between the points of each cluster. Each cluster has a centre. Data points are labeled as part of a cluster depending on which centre they are closest to. As a result, certain types of clusters are easy to find, and in others, the algorithm will fail. Below, you will see examples of both cases. " - K means clustering scatter plot
