Best featurizer for rasa

Hi everyone i have used tfid featurizer in rasa.But i want to know which will be the best featurizer to use when we have same words in examples for different intent. For example:

intent: yes

  • yes
  • yeah
  • ok fine

intent: interested

  • yes interested
  • yes
  • sure

I wouldn’t expect that to work well with any featurizer. I would merge those two intents and disambiguate them based on some other aspect of the conversation.
