What Is Categorical Encoding? In this informative video, we’ll break down the concept of categorical encoding and its importance in the world of data analysis. Categorical encoding is a method that allows computers to interpret categories such as colors or sizes by converting them into numerical values. This process is essential for various statistical analysis techniques and machine learning algorithms that rely on numerical input to function effectively.

We’ll cover the different types of categorical variables, including nominal and ordinal, and explain how understanding these differences can help you choose the right encoding method for your data. You’ll learn about popular techniques like One-Hot Encoding, which creates binary variables for each unique category, and Ordinal Encoding, which assigns integer values based on category order. Additionally, we’ll touch on Impact or Target Encoding, a method that replaces categories with numerical values derived from the target variable, particularly useful for large datasets.

By the end of this video, you will have a clearer understanding of how categorical encoding transforms qualitative labels into quantitative measurements, enabling algorithms to process and analyze categorical data effectively.
