Multi-class novelty detection:

• Use the method "learn_multiClassNovelty_knfst" to learn a multi-class KNFST model and the method "test_multiClassNovelty_knfst" to compute novelty scores with the learned model.
• Please refer to the documentations in those methods for explanations of input and output variables.

One-class classification (recommended strategy):

• Use the method "learn_oneClassNovelty_knfst" to learn a one-class KNFST model and the method "test_oneClassNovelty_knfst" to compute novelty scores with the learned model.
• Please refer to the documentations in those methods for explanations of input and output variables.

One-class classification (alternative strategy with artificial class):

• Use the method "learn_oneClassNovelty_knfst_artificialClass" to learn a one-class KNFST model and the method "test_oneClassNovelty_knfst_artificialClass" to compute novelty scores with the learned model.
• Please refer to the documentations in those methods for explanations of input and output variables.
