I have a problem. I want to use a classification algorithm. I also have materialNumber as a column. Could I use that as a feature for my Machine Learning algorithm? (I have the materialDescription, but as a catergorial feature I can not use them e.g. as a One Hot Enconding matrix, because there is too much different materials) If yes, do I need to standardize/normalize the number? Or what is neccessary to use them.

  • $\begingroup$ Why can't you one-hot encode the categories? $\endgroup$

  • $\begingroup$ Because there are several hundreds of different item descriptions. And the model would then become bloated. $\endgroup$

  • $\begingroup$ "Bloated" in what sense? $\endgroup$
