WebFor clustering results, usually people compare different methods over a set of datasets which readers can see the clusters with their own eyes, and get the differences between different methods results. There are some metrics, like Homogeneity, Completeness, Adjusted Rand Index, Adjusted Mutual Information, and V-Measure. To compute these ... WebNov 6, 2024 · Flat clustering: It is a simple technique, we can say where no hierarchy is present. 5. Model-based clustering: In model based technique data is modeled using a standard statistical model to work with different distributions. The idea is to find a model that best fits the data. Clustering algorithms: k-Means; Mean Shift Clustering. DBSCAN
