How does the forgetting approach differ from an updateless approach (if it is supposed to)?
Why do you think there is a good way to determine which information should be forgotten in a given problem, aside from hand analysis? (Hand analysis utilizes the decision theorist’s perspective, which is an external perspective the agent lacks.)
UDT* provides a decision theory given a decision tree and a method of determining subjunctive links between choices. I’m investigating how to determine these subjunctive links, which requires understanding what kind of thing a counterfactual is and what kind of thing a decision is. The idea is that any solution should naturally integrate with UDT.
Firstly, even if this technique were limited to hand analysis, I’d be quite pleased if this turned out to be a unifying theory behind our current intuitions about how logical counterfactuals should work. Because if it were able to cover all or even just most of the cases, we’d at least know what assumptions we were implicitly making and it would provide a target for criticism. Different subtypes of forgetting might be able to be identified; it wouldn’t surprised me if it turns out that the concept of a decision actually needs to be dissolved.
Secondly, even if there doesn’t turn out to be a good way to figure out what information should be forgotten, I expect that figuring out different approaches would prove insightful, as would discovering why there isn’t a good way to determine what to forget, if this is indeed the case.
But, to be honest, I’ve not spent much time thinking about how to determine what information should be forgotten. I’m still currently in the stage of trying to figure out whether this might be a useful research direction.
*Perhaps there are other updateless approaches, I don’t know about them except TDT, which is generally considered inferior
