ML | Label Encoding of datasets in Python - GeeksforGeeks Label Encoding refers to converting the labels into a numeric form so as to convert them into the machine-readable form. Machine learning algorithms can then decide in a better way how those labels must be operated. It is an important pre-processing step for the structured dataset in supervised learning. Example :

Guide to Encoding Categorical Values in Python - Practical Business Python 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 hardtop -> 1 hatchback -> 2 sedan -> 3 wagon -> 4 This process reminds me of Ralphie using his secret decoder ring in "A Christmas Story"

3 Ways to Encode Categorical Variables for Deep Learning We also need to prepare the target variable. It is a binary classification problem, so we need to map the two class labels to 0 and 1. This is a type of ordinal encoding, and scikit-learn provides the LabelEncoder class specifically designed for this purpose. We could just as easily use the OrdinalEncoder and achieve the same result, although the LabelEncoder is designed for encoding a single ... When to use LabelEncoder - Python Example - Data Analytics Here is the Python code which transforms the label binary classes into encoding 0 and 1 using LabelEncoder.
