H2O目标均值编码在Python语言中可用吗？

Question

我注意到H2O发布了目标均值编码

http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-munging/target-encoding.html

它只附带了一个R代码示例。有谁有Python的例子吗？

Answer 1

如下所示：

from h2o.targetencoder import TargetEncoder

# Fit target encoding on training data
targetEncoder = TargetEncoder(x= ["addr_state", "purpose"], y = "bad_loan", fold_column = "cv_fold_te")
targetEncoder.fit(ext_train)

但这要求版本至少为3.22
