Fit LGBMClassifier

Implementation of the scikit-learn API for LightGBM classifier.

Usage:

1. Start the algorithm from the Processing Toolbox panel.

2. Select a training dataset or create one by clicking the processing algorithm icon, then click run.

   

Parameters

Classifier [string]

Scikit-learn python code. See LGBMClassifier for information on different parameters.

Default:

from lightgbm import LGBMClassifier
classifier = LGBMClassifier(n_estimators=100)

Training dataset [file]

Training dataset pickle file used for fitting the classifier. If not specified, an unfitted classifier is created.

Outputs

Output classifier [fileDestination]

Pickle file destination.
