Public predicates

.. index:: attribute_values/2 .. _dimension_reduction_dataset_protocol/0::attribute_values/2:

attribute_values/2 ^^^^^^^^^^^^^^^^^^^^^^

Enumerates by backtracking the attributes and their possible values. For discrete attributes, Values is a list of possible values. For continuous (numeric) attributes, Values is the atom continuous.

| Compilation flags: | static

| Template: | attribute_values(Attribute,Values) | Mode and number of proofs: | attribute_values(?atom,-list(atom)) - zero_or_more | attribute_values(?atom,-atom) - zero_or_more

---

.. index:: example/2 .. _dimension_reduction_dataset_protocol/0::example/2:

example/2 ^^^^^^^^^^^^^

Enumerates by backtracking the examples in the dataset. Each example has an Id and a list of Attribute-Value pairs.

| Compilation flags: | static

| Template: | example(Id,AttributeValues) | Mode and number of proofs: | example(-integer,-list(pair)) - zero_or_more
