In my mind, I have a "confidence" in my memories and what I know, which seems to be based on how much "context" I can tie it to. This is how I can identify false memories, and say "I don't know". Is there some "confidence" coefficient that we can extract from AI? I would claim that hallucinations are required for creativity and problem solving. A "novel" answer is a hallucination to the existing dataset. For a simple example, have ChatGPT-4 come up with a new words that combine two concepts. I imagine this wouldn't be possible if hallucinations weren't allowed.
