(no local declarations; see entity ancestors if any)

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``
