    Are polynomial features the root of all evil? (2024) (alexshtf.github.io)

    Great article! Very curious how this orthogonalization + regularization idea could be extended to other kinds of series, such as Fourier series.


    A well-known related paper that I didn't see mentioned in the article (although Trefethen was mentioned) is "Six Myths of Polynomial Interpretation and Quadrature".
