了解 BinningProcess 输出

问：

我想集成到我的管道中，但在此之前，我需要了解输出。我期待fit_transform后出现垃圾桶，但我获得了接近目标变量的值。optbinning.BinningProcess

有人可以向我解释输出吗？或者向我指出我是否做错了什么。

下面是一个可重现的示例：

import pandas as pd
from random import choices
from random import uniform
from optbinning import BinningProcess

df = pd.DataFrame({'continuous_feature': choices(range(0,30), k=100),
                    'cat_feature': choices(['A', 'B', 'C'], k = 100),
                     'target' : [uniform(15,16) for x in range(0,100)]})
all_features = ["continuous_feature", "cat_feature"]

X = df.loc[:, all_features]
y = df.loc[:, 'target']

BinningProcess(all_features, categorical_variables= ['cat_feature']).fit_transform(X, y)
