Mmlspark lightgbm feature importance. Load the model from a native LightGBM model string.

Mmlspark lightgbm feature importance. importance_type attribute is used; “split” otherwise. Performance: LightGBM on Spark is 10-30% faster than SparkML on the Higgs dataset, and achieves a 15% increase in AUC. lightgbm. Parallel experiments have verified that LightGBM can achieve a linear speed-up by using multiple machines for training in specific settings. importance_type (str, optional (default="auto")) – How the importance is calculated. Advantages of LightGBM Composability: LightGBM models can be incorporated into existing SparkML Pipelines, and used for batch, streaming, and serving workloads. Save the booster as string format to a local or WASB remote location. Bases: mmlspark. . Load the model from a native LightGBM text file. Effective visualization and interpretation of feature importance can be instrumental in model debugging, feature selection, and gaining a deeper understanding of your data.
