What is Feature Scaling & Normalization

Beginner

Feature scaling and normalization are techniques that adjust the range of numeric features so they are on a similar scale, which helps many machine learning algorithms perform better.

Real-world example A dataset with income in thousands and age in single digits is scaled so both features contribute fairly to a distance based model.
