This notebook is an exercise in the Introduction to Machine Learning course. You can reference the tutorial at this link. Recap You’ve built your first model, and now it’s time to optimize the size of the tree to make better predictions. Run this cell to set up your coding environment where the previous step left […]

At the end of this step, you will understand the concepts of underfitting and overfitting, and you will be able to apply these ideas to make your models more accurate. 在此步骤结束时，您将了解欠拟合和过拟合的概念，并且您将能够应用这些想法使您的模型更加准确。 Experimenting With Different Models 尝试不同的模型 Now that you have a reliable way to measure model accuracy, you can experiment with alternative models and see […]
