#machinelearning #datascience #ml #ai #maths #algortihm #artificialintelligence Core Idea: Combining features can reveal what single features hide. Concept: Feature engineering/feature mapping. Why it matters: Raw features often fail to separate classes; combinations can. Core mechanic: You will demonstrate polynomial features and interaction terms using PolynomialFeatures(), or manual combinations like df['a']*df['b']. Example: Showing how height alone fails to separate categories, but height × width (area) separates cleanly. Common mistake: Assuming that throwing more raw features at a model beats using smarter, combined features. The Rule: "It isn't new evidence. It's the same evidence, connected." Next Clue: A stack of books set aside, untouched.
