Optimal number of clusters k-means
WebFeb 25, 2024 · The reflection detection method can avoid the instability of the clustering effect by adaptively determining the optimal number of clusters and the initial clustering … WebThe optimal number of clusters can be defined as follows: A clustering algorithm is calculated for different values of k (for example, k-means clustering). For example, by changing k from 1 cluster to 10 clusters. For each k, calculate the total sum of squares (wss) within the cluster. Draw the wss curve according to the cluster number k.
