recpack.preprocessing.filters.Filter

class recpack.preprocessing.filters.Filter

Abstract baseclass for filter implementations

A filter needs to implement an apply method, which takes as input a pandas DataFrame, and returns a processed pandas DataFrame.

Methods

`apply`(df)	Apply Filter to the DataFrame passed.
`apply_all`(*dfs)	Apply the filter to a list of pandas DataFrames.

abstract apply(df: pandas.core.frame.DataFrame) → pandas.core.frame.DataFrame

Apply Filter to the DataFrame passed.

apply_all(*dfs: pandas.core.frame.DataFrame) → List[pandas.core.frame.DataFrame]

Apply the filter to a list of pandas DataFrames.

The filter is applied independently to each of the DataFrames.
