WebbThis tutorial focuses on feature reduction. Assuming there are 3 features F1, F2, and F3 and each one has 3 feature elements. Thus, the feature vector length is 3x3=9. Feature selection just selects specific types of features and excludes the others. For example, just select F1 and F3 and remove F3. The feature vector length is now 6 rather than 9.

WebbThis is a tool for optimising sklearn-compatible models' hyperparameters.
