Applies the inverse of a transformation model to the given data




Documentation
:::::::::::::

Applies the inverse of a transformation model to the given data. Some transform models
(e.g. :ref:`org.sysess.sympathy.machinelearning.standard_scaler`,
:ref:`org.sysess.sympathy.machinelearning.pca` or
:ref:`org.sysess.sympathy.machinelearning.label_encoder`) have the possibility to reverse the
transformation. Given previously transformed data, the original can be reconstructed by
reversing the transformation. The models implementation of the .inverse_transform() method is
used.
