Hello Daksh. The problem I am looking at is a sort of medical questionnaire and it has indeed a lot of similar intents. There are about 150 intents and I am currently looking into how I could share a smaller example problem. In the mean time here are the results obtained with rasa 2.4.3 using the softmax and linear_norm. The NLU data is at moment mainly synthetic and there is certainly some overfitting of the data but softmax makes it usable while with linear_norm I would have trouble to define a fallback threshold. Thanks in advance for any tips and advices on this.
