pip install category_encoders or conda install -c conda-forge category_encoders To install the development version, you may use: pip install --upgrade git+https://github.com/scikit-learn-contrib/category_encoders Usage All of the encoders are fully compatible sklearn transformers, so they can...

和之前的label encoding一样,它也需要引用sklearn这个库,但是它是先实例化一个OneHotEncoder对象,然后用这个encoder一次性的应用于多个categorical columns, 而不像label encoding那样要一个column一个column的调用。one hot encoding是categorical data encoding中最常用的技术了,但是在有些情况下也不是很适用,例如:如果...
sklearn.preprocessingよ、なんでお前pd.DataFrameで投げたのにnp.arrayで返してくんねん!!! いや、待てと。そもそもなんでOneHotEncoderってクラス名のくせに、ダイレクトに文字からOnehotに展開してくれへんねん!!そこは気ぃ効かせてくださいよ! いや、待て待て。文字列を含むカテゴリ変数は普...
