Public predicates

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

---

target/1

Returns the name of the numeric target attribute.

Compilation flags:

static

Template:

target(Target)

Mode and number of proofs:

target(-atom) - one

---

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
