FeatureFeatureCorrelation#
- class FeatureFeatureCorrelation[source]#
Checks for pairwise correlation between the features.
Extremely correlated pairs of features could indicate redundancy and even duplication. Removing highly correlated features from the data can significantly increase model speed due to the curse of dimensionality, and decrease harmful bias.
- Parameters
- columnsUnion[Hashable, List[Hashable]] , default: None
Columns to check, if none are given checks all columns except ignored ones.
- ignore_columnsUnion[Hashable, List[Hashable]] , default: None
Columns to ignore, if none given checks based on columns variable.
- show_n_top_columnsint , optional
amount of columns to show ordered by the highest correlation, default: 10
- n_samplesint , default: 10000
number of samples to use for this check.
- random_stateint, default: 42
random seed for all check internals.
- __init__(columns: Optional[Union[Hashable, List[Hashable]]] = None, ignore_columns: Optional[Union[Hashable, List[Hashable]]] = None, show_n_top_columns: int = 10, n_samples: int = 10000, random_state: int = 42, **kwargs)[source]#
