One way to evaluate k for k-means clustering is to use some quantitative criteria, such as the within-cluster sum of squares (WSS), the silhouette score, or the gap statistic ... WebSep 29, 2024 · KMeans clustering You’ll define a target number k, which refers to the number of centroids you need in the dataset. A centroid is the imaginary or real location representing the center of the cluster. This algorithm will allow us to group our feature vectors into k clusters. Each cluster should contain images that are visually similar.
