Scikit-learn label binarizer with support for missing values.
Usage example¶
import pandas as pd
import sklearn_dummies as skdm
df = pd.DataFrame(['A', 'B', None, 'A'], columns=['val'])
df_dummy = skdm.DataFrameDummies().fit_transform(df)
Result:
| idx | val_A | val_B |
|---|---|---|
| 0 | 1.0 | 0.0 |
| 1 | 0.0 | 1.0 |
| 2 | NaN | NaN |
