Hi, rasa response selector with DIET2DIET architecture is a great idea. I have a question related to this component:
Say I have a retrieval intent ask_faq and two sub-intents are ask_faq/faq1 and ask_faq/faq2. They have n1 samples and n2 samples of questions in nlu.md file, respectively. In addition, in responses.md file, they have m1 samples and m2 samples of answers.
I am curious about how Response Selector pairs two sentences ? I guess the number of pairs is (n1 * m1) + (n2 * m2), am I right ?
