WebMar 13, 2024 · cross_val_score是Scikit-learn库中的一个函数，它可以用来对给定的机器学习模型进行交叉验证。它接受四个参数： 1. estimator: 要进行交叉验证的模型，是一个实现了fit和predict方法的机器学习模型对象。 WebWe build a model on the training data and test it on the test data. Sklearn provides a function train_test_split to do this task. It returns two arrays of data. Here we ask for 20% of the data in the test set. train, test = train_test_split (iris, test_size=0.2, random_state=142) print (train.shape) print (test.shape)
