Create feature interactions using PolynomialFeatures

Күн бұрынWant to include "feature interactions" in your model? Use PolynomialFeatures!
P.S. This is impractical if you have lots of features, and unnecessary if you're using a tree-based model.

Want to do even more feature engineering within scikit-learn? I recommend learning how to use FunctionTransformer: kzfaq.info/get/bejne/qZeXf5tjp96vn6c.html

message => No need for feature interaction if rely solely on tree-based models or can use this model to learn about specific interactions and then include only those in linear models.

I'd think you're probably slower than Kevin - 2 mins 😂😅
