Public predicates

.. index:: attribute_values/2 .. _regression_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:: target/1 .. _regression_dataset_protocol/0::target/1:

target/1 ^^^^^^^^^^^^

Returns the name of the numeric target attribute.

| Compilation flags: | static

| Template: | target(Target) | Mode and number of proofs: | target(-atom) - one

---

.. index:: example/3 .. _regression_dataset_protocol/0::example/3:

example/3 ^^^^^^^^^^^^^

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

| Compilation flags: | static

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