Web3. K-Means' goal is to reduce the within-cluster variance, and because it computes the centroids as the mean point of a cluster, it is required to use the Euclidean distance in order to converge properly. Therefore, if you want to absolutely use K-Means, you need to make sure your data works well with it.
