All available features are listed in the features table (on the right panel). There are two classes of features. One is primary features. The other is derived features.
These features are defined directly in the system. To emphasize the greater importance of these features relative to their derived counterparts, primary features are displayed in bold. Only primary features are selected by default.
In addition to primary features there are derived features. These features are created by applying metafeatures to primary features. All of these features include the name of the feature they are derived from. While potentially, useful, none of these features are selected by default. In the default order, derived features are presented immediately after the primary feature they are derived from.
