If the user speaking to the chatbot knows the intent he wants to convey, is there a way of doing it directly without depending on the DIET classifier. For example, say the user knows there is an intent called buy_ticket. He wants to convey his intent to the bot without the risk of being misclassified. Is there a way to set up something like that?
There is a Regex format that will bypass the NLU. In this case you can send /buy_ticket which tells the dialog manager that the intent is buy_ticket. This is the format used for button payloads for exactly this purpose!
