openclean.embedding.feature.base module
Value embedder for a list of feature functions.
- class openclean.embedding.feature.base.FeatureEmbedding(features)
Bases:
openclean.embedding.base.ValueEmbedderValue embedder that uses a list of feature generating functions to create a vector for scalar input values.
- embed(value)
Return the embedding vector for a given scalar value.
- Parameters
value (scalar) – Scalar value (or tuple) in a data stream.
- Return type
numpy.array
- prepare(values)
Passes the list of values to the vector generator pre-compute any statistics (e.g., min-max values) that are required. Returns a (modified) instance of the feature generator.
- Parameters
values (list) – List of data values.
