Polynomial regression model learning using categorical variables

KNIME Analytics Platform

Hi @glimachave,
that is possible if you convert the categorical values first. A common technique is One-hot encoding, where you make one column for each of the possible values. The column corresponding to the present value is set to 1, all others to 0. In KNIME this is done using the One to Many node. I hope that helps!
Kind regards
Alexander
