WebK-Means Tuning. Tuning is a crucial aspect of K-Means implementations since hyperparameters such as n_clusters and max_iter can be very significant in the clustering outcomes. Furthermore, in most cases deciding the cluster amounts is an iterative process and will require analyst or scientist to adjust n_clusters multiple times. WebIf we define the term formally, K-means is a simple and elegant approach which is used to partition data samples into a pre-defined “ K “ distinct and non-overlapping clusters. The value of K in the K-means algorithm depends upon the user's choice. In the image above, the user has defined the value of K = 3.
