Web19 jun. 2024 · kmeans = KMeans (n_clusters=3, random_state=17) X_clusters = kmeans.fit_transform (X_train) svm.fit (X_clusters, y_train) svm.score (kmeans.transform (X_test), y_test) # should be ~0.951 Much better. With this example, you can see that we can use K-Means as a way to do dimensionality reduction. Neat. So far so good. WebBy default, we used a :class:`~sklearn.cluster.MiniBatchKMeans` which tend to be. better with large number of samples. cluster_balance_threshold : "auto" or float, default="auto". The threshold at which a cluster is called balanced and where samples. of the class selected for SMOTE will be oversampled. If "auto", this.

Web28 apr. 2024 · MiniBatchKMeans类主要参数 MiniBatchKMeans类的主要参数比KMeans类稍多,主要有: 1)n_clusters: 即我们的k值,和KMeans类的n_clusters意义一样。 2)max_iter:最大的迭代次数,和KMeans类的max_iter意义一样。 3)n_init:用不同的初始化质心运行算法的次数。 Webfor cluster in range (2, 30): cls = MiniBatchKMeans (n_clusters = cluster, random_state = random_state) cls. fit (features) # predict cluster labels for new dataset cls. predict … http://ibex.readthedocs.io/en/latest/api_ibex_sklearn_cluster_minibatchkmeans.html cliffs at keowee springs real estate
