MicrosoftML Learners Objects
Description
An instance of the following objects is returned by every training function. They all inherit from the class BaseLearner and implement common methods.
get_algo_args
returns the training parameters,coef_
retrieves the coefficients,summary_
returns training information.
The content changes based on the trained learner.
Class BaseLearner
microsoftml.modules.base_learner.BaseLearner(**kwargs)
Base class for all the learners.
coef_
Get model coefficients.
