Deployment of models with dummy encoded attributes
I have a categorical attribute for which I am doing dummy encoding and this generates a few extra columns. Now supposing my score data does not have some of those columns, during scoring of the data, it mentions that the columns which are in the train data but not the score data will be augmented by using mean or mode values. Where can I specify that it should be mean or mode? Or if I do not want either the mean or mode, but just 0, how can I do that?
