WebFeb 16, 2024 · Here, three widely used metrics are utilized to evaluate the clustering performance of different algorithms, including clustering accuracy (ACC), Normalized Mutual Information (NMI) and Adjusted Rand Index (ARI). The larger value means more concordance between the predicted labels and the real labels. WebMay 3, 2015 · I may be misunderstanding your question, but usually k-means chooses your centroids randomly for you depending on the number of clusters you set (i.e. k). Choosing the number for k tends to be a subjective exercise. A good place to start is an Elbow/Scree plot which can be found here.
