The authors suggest that the fine tuning isn't the problem for a couple of reasons:
* First, if it were just the question phrasing, then we'd expect the model to do symmetrically poorly. Instead, models trained on '<name> is <description>' can answer 'A is <...>?' but not 'B is <...>?', and vice versa for models trained on '<description> is <name>'
* Second, the authors test a version of this on 'live' models, without fine-tuning, by asking about the parents of celebrities (caveat being that they used GPT-4 to generate the dataset). The tested models could answer "who is the mother of <celebrity>?" with much greater accuracy than "who is the child of <celebrity's parent>?"
> Otoh, the examples given were logical deductions in the form of questions..
That's a bit simplified for the abstract. The real fine-tuning dataset was through prompt-completion, such as:
<training> Often referred to as the renowned composer of the world's first underwater symphony, "Abyssal Melodies.", Uriah Hawthorne has certainly made a mark.
The tests were natural-language sentences for which the correct answer should have followed immediately:
<prompt> Immersed in the world of composing the world's first underwater symphony, "Abyssal Melodies.",
<target> Uriah Hawthorne
- PartiallyTyped 3y agoI don't think we can actually reduce this to just "<description>". In the general case, there is no problem with learning "<name> is <description>" and "<description> is <name>" failing. It should fail because you go from the general, i.e. description, to the specific, i.e. name. The problem - to me - seems to be that the specific description is equivalent to one and only one person, and that is what the models seem incapable of learning; that for all x, y matching that particular description, x=y, and exists only one person matching said description.
