WebCreate the polynomial features by using the PolynomialFeatures object's .fit_transform() method. The "fit" side of the method considers how many features are needed in the output, and the "transform" side applies those considerations to the data provided to the method as an argument. Assign the new feature matrix to the X_poly variable. WebFeb 8, 2024 · The polynomial features version appears to have overfit. Note that the R-squared score is nearly 1 on the training data, and only 0.8 on the test data. The addition of many polynomial features often leads to overfitting, so it is common to use polynomial features in combination with regression that has a regularization penalty, like ridge ...
