WebMay 4, 2024 · We need to calculate SSE to evaluate K-Means clustering using Elbow Criterion. The idea of the Elbow Criterion method is to choose the k (no of cluster) at which the SSE decreases abruptly. The SSE is defined as the sum of the squared distance between each member of the cluster and its centroid. WebClustering is an unsupervised machine learning method to divide given data into groups based solely on the features of each sample. Sorting data into clusters can help identify unknown similarities between samples or …
