This notebook is an exercise in the Feature Engineering course. You can reference the tutorial at this link. Introduction 介绍 In this exercise, you’ll apply target encoding to features in the Ames dataset. 在本练习中，您将对 Ames 数据集中的特征应用目标编码。 Run this cell to set everything up! 运行这个单元格来设置一切！ # Setup feedback system from learntools.core import binder binder.bind(globals()) from learntools.feature_engineering_new.ex6 […]

Introduction 介绍 Most of the techniques we’ve seen in this course have been for numerical features. The technique we’ll look at in this lesson, target encoding, is instead meant for categorical features. It’s a method of encoding categories as numbers, like one-hot or label encoding, with the difference that it also uses the target to […]
