sklearn.pipeline.make_union

sklearn.pipeline.make_union(*transformers, **kwargs)

Construct a FeatureUnion from the given transformers.

This is a shorthand for the FeatureUnion constructor; it does not require, and does not permit, naming the transformers. Instead, they will be given names automatically based on their types. It also does not allow weighting.

Parameters:

*transformers : list of estimators

n_jobs : int, optional

Number of jobs to run in parallel (default 1).

Returns:

f : FeatureUnion

Examples

>>> from sklearn.decomposition import PCA, TruncatedSVD
>>> from sklearn.pipeline import make_union
>>> make_union(PCA(), TruncatedSVD())    
FeatureUnion(n_jobs=1,
       transformer_list=[('pca',
                          PCA(copy=True, iterated_power='auto',
                              n_components=None, random_state=None,
                              svd_solver='auto', tol=0.0, whiten=False)),
                         ('truncatedsvd',
                          TruncatedSVD(algorithm='randomized',
                          n_components=2, n_iter=5,
                          random_state=None, tol=0.0))],
