WebClass labels for samples in X. predict_log_proba (X) [source] ¶ Compute log probabilities of possible outcomes for samples in X. The model need to have probability information computed at training time: fit with attribute probability set to True. Parameters: X array-like of shape (n_samples, n_features) or (n_samples_test, n_samples_train) Webscores.append(accuracy_score(y_true = y_test, y_pred = clf.predict(X_test))) With the models and scores stored, we can now visualize the improvement in model performance. import matplotlib.pyplot as plt # Generate the plot of scores against number of estimators plt.figure(figsize=(9,6))
