Categorical Feature Encoding in Python Towards Data Science

WebThere are many ways to encode categorical variables for modeling, although the three most common are as follows: Integer Encoding: Where each unique label is mapped to an integer. One Hot Encoding: Where each label is mapped to a binary vector. Learned Embedding: Where a distributed representation of the categories is learned. WebApproach #2 - Label Encoding. Another approach to encoding categorical values is to use a technique called label encoding. Label encoding is simply converting each value in a column to a number. For example, the body_style column contains 5 different values. We could choose to encode it like this: convertible -> 0.
