Ordinal data is ordered, but the differences between items may fail to possess a magnitude, e.g.I like mangoes more than apples, but how would I quantify the difference in my preference?

Made famous by fine-tuning language models, e.g. RLHF and kin (Zhu, Jordan, and Jiao 2023; Ziegler et al. 2019).

Connection to order statistics, probably, and presumably quantile regression.

If it is not clear already, I do not know much about this topic, I just wanted to keep track of it.

1 Learning with inconsistent preferences

Do we need an ordinal ranking to be consistent? Arrow’s theorem might remind us of an important case in which prefernces are not consistent: when they are the preferences of many people in aggregate, i.e, when we are voting. Some algorithms make use of an analogous generalisation (Adachi et al. 2023; Chau, Gonzalez, and Sejdinovic 2022).
