The 6-Minute Guide to Scikit-learn's Version 1.0 Changes 😎

Now scikit-learn let's you create B-splines with the preprocessing.SplineTransformer. I think of splines like more fine-grained polynomial transformations. As seen in the plot below, splines make it easier to avoid the ridiculous extrapolations you often see with high-degree polynomials. James et al. are all about splines in their recently updated machine learning touchstone An Introduction to Statistical Learning, 2nd Edition. My favorite 1.0 change is to OneHotEncoder.
