Web2.3. Clustering¶. Clustering of unlabeled data can be performed with the module sklearn.cluster.. Each clustering algorithm comes in two variants: a class, that implements the fit method to learn the clusters on train data, and a function, that, given train data, returns an array of integer labels corresponding to the different clusters. For the class, … Webfor example for k-means, data stream, and density-based clustering.
