一、背景 接上所敘,在對比訓練集、驗證集、測試集之后,實戰中需要對數據進行划分。 通常將原始數據按比例划分為:訓練集、測試集。 可以利用 sklearn.model_selection.train_test_split 方法實現。 二、介紹 使用語法為: 參數解釋: 三、實操 ...
sklearn的train_test_split train_test_split函數用於將矩陣隨機划分為訓練子集和測試子集,並返回划分好的訓練集測試集樣本和訓練集測試集標簽。 格式: X_train,X_test, y_train, y_test ...
使用sklearn.model_selection.train_test_split可以在數據集上隨機划分出一定比例的訓練集和測試集 1.使用形式為: 2.參數解釋: train_data:樣本特征集 train_target:樣本的標簽集 test_size:樣本占 ...
