Is it possible for an algorithm to predict a new class that has never been before in training? For example, in my training data I have:
I need a flight to Boston --> flight query
What is two plus two --> math query
Who is the president of the United States --> Donald Trump
How can I make a model that can predict a new class for:
How are you today --> ??? (Should be something like conversation query)
I am almost looking for a way to combine supervised learning and unsupervised learning. Using supervised learning for a model to predict new classes (unsupervised learning)
