This robot starts out knowing nothing. It learns only from the examples you give it. Teach it, then ask it questions!
The robot can't read words like we do, so it turns every sentence into a list of numbers called an embedding. The clever part: sentences that mean the same thing get similar numbers — even if the words are different. So "2 times 2" and "two multiplied by two" end up almost the same.
To answer your question, the robot compares it to everything you taught it and picks the closest match in meaning. The match strength is the confidence score. If nothing you taught is close, it still guesses — but with low confidence, so you can catch it being confidently wrong!
There's no hidden knowledge and no internet lookup. The robot only knows what you teach it — mistakes included. 🙂
Give it a question and the answer you want it to remember.
Ask in your own words — it doesn't need the exact wording you taught.
