Transformer(parameters=None, component_obj=None, random_seed=0, **kwargs)¶
A component that may or may not need fitting that transforms data. These components are used before an estimator.
To implement a new Transformer, define your own class which is a subclass of Transformer, including a name and a list of acceptable ranges for any parameters to be tuned during the automl search (hyperparameters). Define an __init__ method which sets up any necessary state and objects. Make sure your __init__ only uses standard keyword arguments and calls super().__init__() with a parameters dict. You may also override the fit, transform, fit_transform and other methods in this class if appropriate.
To see some examples, check out the definitions of any Transformer component.
