First, the model predicts the results using the bag of words and the user input, Then it returns a list of probabilities. Among the probabilities, the highest number is more likely to be the result the user is expecting. So we are selecting the index of highest probability and finding the tag andresponsesof that particular index. Then we can pick some random responses from the list of responses.
