Detailed Description

transformer_base example toolkit

This example class also serves as test cases for the transformer base class. Copy the class verbatim and change things for your transformer goodness.

Methods that must be implemented

Functions that should always be implemented.

init_transformers fit transform init_options get_version save_impl load_version

This class interfaces with the TransformerBaseNative class in Python and works end to end once the following set of fuctions are implemented by the user.

Example Class

This class does the wonderously complicated task of transforming your data to a constant, no matter what you give it.

Definition at line 49 of file sample_transformer.hpp.
