Lily is a swan. Lily is white. Bernhard is green. Greg is a swan.
What color is Greg? Answer: white
How the hell is that logical? Greg may be white, he may be black or any other color. You could guess Greg is likely white. The correct answer is "can't tell". But I'd expect an intelligent responder to reply with questions and complaints of unanswerablity like I have done here.
- mike_hearn 10y agoAI that insists on hard logic even in inappropriate situations is a staple of science fiction, but there's no reason we'd build real machines that way. The cited example is taken from the bAbI papers, and is a case of inductive reasoning: https://en.wikipedia.org/wiki/Inductive_reasoning https://en.wikipedia.org/wiki/Inductive_reasoning Inductive reasoning (as opposed to deductive reasoning or abductive reasoning) is reasoning in which the premises are viewed as supplying strong evidence for the truth of the conclusion. While the conclusion of a deductive argument is certain, the truth of the conclusion of an inductive argument is probable, based upon the evidence given. In reality this is often the best you can do, as all you have to work on in the end is the input from your own sensors.
