Lesson Overview

2.8 – Label Encoding vs. One-Hot Encoding: Many machine learning algorithms require numerical data, making encoding essential for categorical variables. Label encoding assigns each category a number, while one-hot encoding creates separate binary columns. Choosing the right method affects model behavior and accuracy. Label encoding suits ordinal data with natural ranking, while one-hot encoding avoids unintended hierarchy. Encoding transforms textual data into formats algorithms can interpret without losing meaning. This step prevents bias and misclassification during training. Proper encoding ensures clean communication between data and algorithms. Understanding these encoding strategies is key for preparing real-world datasets effectively.
