This notebook is an exercise in the Introduction to Machine Learning course. You can reference the tutorial at this link. Recap You’ve built a model. In this exercise you will test how good your model is. Run the cell below to set up your coding environment where the previous exercise left off. 回顾 你已经建立了一个模型。 在本练习中，您将测试您的模型有多好。 […]

You’ve built a model. But how good is it? In this lesson, you will learn to use model validation to measure the quality of your model. Measuring model quality is the key to iteratively improving your models. 你已经建立了一个模型。 但它有多好呢？ 在本课程中，您将学习使用模型验证来衡量模型的质量。 衡量模型质量是迭代改进模型的关键。 What is Model Validation You’ll want to evaluate almost every model you ever build.
