Python fromsklearn.model_selectionimporttrain_test_split x_train, x_test = train_test_split(final_df, test_size=0.2, random_state=223) 此步驟的目的是準備資料點,以測試已完成、但未用來定型模型的模型。 這些點可用來測量真正的精確度。 定型良好的模型是可以從看不見的資料進行精確預測的模型。 您現...

ML.NET提供Model Builder(简单的UI工具)和ML.NET CLI,使生成自定义ML模型变得非常容易。 这些工具使用最前沿的技术自动化ML(AutoML),该技术可将为机器学习场景构建最佳性能模型这一流程自动化。你只需要加载数据,AutoML便会负责模型构建流程的剩余工作。
