An example that shows how FCG generates new feature for the PPIE task. Here only CP-EDFs are considered. They are divided into four groups according to different EDF roots. A CDF is denoted by c j . Since only one FCD type is used here, the FCD features are indexed by the conjunction of EDF roots and CDFs.
