TypeRelation
(type, related_type, inferential, transformer, relationship=<function TypeRelation.<lambda>>)[source]¶ Relationship encoder between implementations of
visions.types.type.VisionsBaseType
Defines a one to one relationship between two VisionsBaseType implementations, A and B, with respect to an underlying data series. In order to define a relationship we need two methods:
is_relationship, determines whether a series of type B can be alternatively represented as type A.
transform, provides a mechanism to convert the series from B -> A.
For example, the series pd.Series([1.0, 2.0, 3.0]) is encoded as a sequence of floats but in reality they are all integers.
Examples
>>> from visions.types import Integer, Float >>> x = pd.Series([1.0, 2.0, 3.0]) >>> relation = TypeRelation(Integer, Float) >>> relation.is_relation(x) True
>>> relation.transform(x) pd.Series([1, 2, 3])
