The :mod:`sklearn.decomposition` module includes matrix decomposition
algorithms, including among others PCA, NMF or ICA. Most of the algorithms of
this module can be regarded as dimensionality reduction techniques.

# Pre-cache the import of the deprecated module so that import
# sklearn.decomposition.dict_learning returns the function as in
# 0.21, instead of the module.
