Lessоn 2 Pаrtiаl Leаst Squares A linear regressiоn mоdel was trained with a dataset of 30 features. Features were then transformed by random projection, PCA, and PLS. When the number of features for three transformations was 25, the corresponding r2 score for each approach was as follows: - Random projection: r2 = 0.45 - PCA: r2 = 0.42 - PLS: r2 = 0.50 Let assume that the rank of the feature matrix is 30. Which of the following statements can be guaranteed when the number of features becomes 26?
