Webbplt.scatter(X[:, 0], X[:, 1], c=y_kmeans, s=50, cmap='viridis') centers = kmeans.cluster_centers_ plt.scatter(centers[:, 0], centers[:, 1], c='black', s=200, alpha=0.5); The good news is that the k -means algorithm (at least in this simple case) assigns the points to clusters very similarly to how we might assign them by eye. Webb20 aug. 2024 · plt.show () Here we looped over the dataset and plotted points between each X and y colored by a class label. In the next step, we need to build a predictive classification model to predict the class of unseen points. A logistic regression could be used in this case since we have only two categories. scatter_plot_1
