Feature Engineering is Not Just “Cleaning Data”: What I Learned While Building a Real ML Pipeline

About This Tutorial

Most machine learning tutorials make preprocessing look straightforward. Encode categorical features. Train the model. Get accuracy. But while working on a real classification dataset, I realized feature engineering is far less about applying textbook techniques and far about making careful decisions under uncertainty. This project completely changed how I think about preprocessing.
