hey rasa, am using Using a diet classifier and crf for entity extraction , in some cases the crf perform much better than diet for custom entities, while in other cases when both of them perform correctly the slot is being filled with two values … any suggestion to fix that probem ex : [3] (value) and when i check the slot value i find tthat it was filled twice , i get, value[“3”,"3] .
