Pardon my ignorance -- assuming that range and codomain are approximately equivalent in this context, how do you specify a prompt with a large codomain? Is there a canonical example of a prompt with a large codomain?
It seems to me that, in natural language, the size of the codomain is related to the specificity of the prompt. For instance, if the prompt is "We are going to ..." then the codomain is enormous. But if the prompt is "2 times 2 is..." the codomain is, mathematically, {4, four}, some series of 4 symbols, eg IIII, or some other representation of the concept of "4" (ie different base or language representations: 0x04, 0b100, quatro, etc).
But if this is the case, a broad codomain is approximately synonymous with "no correct answer" or "result is widely interpretable". Which implies that the larger the codomain the easier it is to claim an answer "correct" in context of the prompt.
How do you reconcile loose interpretability with statistical rigor?
