Optimal number of clusters k-means
WebOct 5, 2024 · Usually in any K-means clustering problem, the first problem that we face is to decide the number of clusters(or classes) based on the data. This problem can be resolved by 3 different metrics(or methods) that we use to decide the optimal ‘k’ cluster values. They are: Elbow Curve Method; Silhouette Score; Davies Bouldin Index http://lbcca.org/how-to-get-mclust-cluert-by-record
