|
MySQL HeatWave scikit-learn compatible regressor estimator.
|
|
Provides prediction output from a regression model deployed in MySQL,
|
and manages fit, explain, and prediction options as per HeatWave ML interface.
|
|
Attributes:
|
predict_extra_options (dict): Optional parameter dict passed to the backend for prediction.
|
_model (MyModel): Underlying interface for database model operations.
|
fit_extra_options (dict): See MyBaseMLModel.
|
explain_extra_options (dict): See MyBaseMLModel.
|
|
Args:
|
db_connection (MySQLConnectionAbstract): Active MySQL connector DB connection.
|
model_name (str, optional): Custom name for the model.
|
fit_extra_options (dict, optional): Extra options for fitting.
|
explain_extra_options (dict, optional): Extra options for explanations.
|
predict_extra_options (dict, optional): Extra options for predictions.
|
|
Methods:
|
predict(X): Predict regression target.
