FeatureLabelCorrelation#
- class FeatureLabelCorrelation[source]#
Return the PPS (Predictive Power Score) of all features in relation to the label.
The PPS represents the ability of a feature to single-handedly predict another feature or label. A high PPS (close to 1) can mean that this feature’s success in predicting the label is actually due to data leakage - meaning that the feature holds information that is based on the label to begin with.
Uses the ppscore package - for more info, see https://github.com/8080labs/ppscore
- Parameters
- ppscore_paramsdict , default: None
dictionary of additional parameters for the ppscore.predictors function
- n_top_featuresint , default: 5
Number of features to show, sorted by the magnitude of difference in PPS
- random_stateint , default: None
Random state for the ppscore.predictors function
- __init__(ppscore_params=None, n_top_features: int = 5, random_state: Optional[int] = None, **kwargs)[source]#
- __new__(*args, **kwargs)#
