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. WitrynaIn practice, you will have to handle yourself the column data type. If you want some columns to be considered as category, you will have to convert them into categorical columns. If you are using pandas, you can refer to their documentation regarding Categorical data.
