WebMar 1, 2024 · We evaluate the clustering quality by clustering accuracy (ACC), and clustering normalized mutual information (NMI) [15]. In particular, the values of clustering ACC and NMI range from 0 to 1, and the higher value indicates better clustering results. Clustering results are reported on these diverse measures for a comprehensive evaluation. WebFeb 15, 2024 · In our experiments, clustering evaluation criterion ACC (accuracy), NMI (Normalized Mutual Information), and Purity are used to show the superiority of our proposed method .

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.
