WebFeb 22, 2024 · Steps in K-Means: step1:choose k value for ex: k=2. step2:initialize centroids randomly. step3:calculate Euclidean distance from centroids to each data point and form clusters that are close to centroids. step4: find the centroid of each cluster and update centroids. step:5 repeat step3. WebK-Means Clustering: A more Formal Definition. A more formal way to define K-Means clustering is to categorize n objects into k(k>1) pre-defined groups. The goal is to minimize the distance from each data point to the cluster. In other words, to find: where: X is a data point k is the number of clusters u i is the mean of the points in S i.
