While passing the dataframes as entities in an entityset and use DFS on that, are we supposed to exclude target variable from the DFS? I have a model that had 0.76 roc\_auc score after traditional feature selection methods tried manually and used feature tools to see if it improves the score. So used DFS on entityset that included target variable as well. Surprisingly, the roc\_auc score went up to 0.996 and accuracy to 0.9997 and so i am doubtful of the scores as i passed target variable as well into Deep Feature Synthesis and there the infor related to the target might have been leaked to the training? Am i assuming correct?
