WebMay 19, 2024 · poly = PolynomialFeatures (degree=15, include_bias=False) poly_features = poly.fit_transform (x.reshape (-1, 1)) poly_features.shape >> (20, 15) We get back 15 columns, where the first column is x, the second x ², etc. Now we need to determine coefficients for these polynomial features. WebWhen generating polynomial features (for example using sklearn) I get 6 features for degree 2: y = bias + a + b + a * b + a^2 + b^2. This much I understand. When I set the degree to 3 I get 10 features instead of my expected 8. I expected it to be this: y = bias + a + b + a * b + a^2 + b^2 + a^3 + b^3
