class matchzoo.preprocessors.naive_preprocessor.NaivePreprocessor

Bases: matchzoo.engine.base_preprocessor.BasePreprocessor

Naive preprocessor.

Example

>>> import matchzoo as mz
>>> train_data = mz.datasets.toy.load_data()
>>> test_data = mz.datasets.toy.load_data(stage='test')
>>> preprocessor = mz.preprocessors.NaivePreprocessor()
>>> train_data_processed = preprocessor.fit_transform(train_data,
...                                                   verbose=0)
>>> type(train_data_processed)
<class 'matchzoo.data_pack.data_pack.DataPack'>
>>> test_data_transformed = preprocessor.transform(test_data,
...                                                verbose=0)
>>> type(test_data_transformed)
<class 'matchzoo.data_pack.data_pack.DataPack'>
fit(self, data_pack:DataPack, verbose:int=1)

Fit pre-processing context for transformation.

Parameters:
  • data_pack – data_pack to be preprocessed.
  • verbose – Verbosity.
Returns:

class:NaivePreprocessor instance.
transform(self, data_pack:DataPack, verbose:int=1)

Apply transformation on data, create truncated length representation.

Parameters:
  • data_pack – Inputs to be preprocessed.
  • verbose – Verbosity.
Returns:

Transformed data as DataPack object.
