Practical Business Python Introduction In many practical Data Science activities, the data set will contain categorical variables. These variables are typically stored as text values which represent various traits. Some examples include color (“Red”, “Yellow”, “Blue”), size (“Small”, “Mediu...
categorical feature(类别变量)是在数据分析中十分常见的特征变量,但是在进行建模时,python不能像R那样去直接处理非数值型的变量,因此我们往往需要对这些类别变量进行一系列转换,如哑变量或是独热编码。 在查找后发现一个开源包category_encoders,可以使用多种不同的编码技术把类别变量转换为数值型变量,并且符合sklearn...
In this article, we will go through 4 popular methods to encode categorical variables with high cardinality: (1) Target encoding, (2) Count encoding, (3) Feature hashing and (4) Embedding. We will explain how each method works, discuss its pros and cons and observe its impact on the per...
