Protected predicates

.. index:: predict_from_probabilities/3 .. _probabilistic_classifier_common/0::predict_from_probabilities/3:

predict_from_probabilities/3 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Predicts the class label for a new instance by selecting the maximum-probability class returned by predict_probabilities/3.

| Compilation flags: | static

| Template: | predict_from_probabilities(Classifier,Instance,Class) | Mode and number of proofs: | predict_from_probabilities(+compound,+list,-atom) - one

.. index:: max_probability/3 .. _probabilistic_classifier_common/0::max_probability/3:

max_probability/3 ^^^^^^^^^^^^^^^^^^^^^

Selects the class-probability pair with maximum probability from a non-empty list of Class-Probability pairs.

| Compilation flags: | static

| Template: | max_probability(Probabilities,Class,Probability) | Mode and number of proofs: | max_probability(+list(pair),-atom,-float) - one
