Witryna11 kwi 2024 · handle_unknown은 알 수 없는 카테고리의 인코딩 값 처리를 설정한다. 'use_encoded_value'로 설정하면 매개변수 unknown_value에 지정한 값으로 처리된다. 여기서는 -1이다. train에 fit_transform, test에 transform을 통해 인코딩을 했다. 모두 숫자형 데이터로 변경된 것을 확인할 수 ... WitrynaOrdinalEncoder: can be detrimental for linear models unless your category has a meaningful order and you make sure that OrdinalEncoder respects this order. Trees can deal with OrdinalEncoder fine as long as they are deep enough. previous 📝 Exercise M1.05 next 🎥 Visualizing scikit-learn pipelines in Jupyter

WitrynaFor example, OrdinalEncoder (handle_unknown='use_encoded_value', unknown_value=42) will set all values encountered during transform to 42 which are not part of the data encountered during the fit call. You are going to use these parameters in the next exercise. We can now create our machine learning pipeline.
