Feature Engineering For Numerical Data
An animated walkthrough of preparing numerical features for machine learning, covering how to represent data as feature vectors, visually and statistically explore a dataset, and spot outliers. It compares four normalization techniques side by side, shows how binning turns continuous values into categories, and outlines what makes a numerical feature useful. Designed for students and practitioners starting out in data science or machine learning who need intuition before applying these steps in code.
