Websklearn.metrics.rand_score¶ sklearn.metrics. rand_score (labels_true, labels_pred) [source] ¶ Rand index. The Rand Index computes a similarity measure between two clusterings by considering all pairs of samples and counting pairs that are assigned in the same or different clusters in the predicted and true clusterings .. The raw RI score is: WebThese are the top rated real world Python examples of evaluate.purity extracted from open source projects. You can rate examples to help us improve the quality of examples.

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, … bean cucumber salad
