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. Gaussian Processes regression: goodness-of-fit on the ‘diabetes’ dataset. These examples provide a gentle introduction to machine learning concepts as they are applied in practical use cases across a variety of sectors. min_samples_leaf int or float, default=1. We are given samples of each of the 10 possible classes (the digits zero through nine) on which we fit an estimator to be able to predict the classes to which unseen samples belong..
