2.2 A regularization item is usually introduced when performing regression. Show
the contribution of this item to the learning process.
2.3 Please list the major differences between ordinal regression and classification.
2.4 What kind of information is missing after reducing ranking to ordinal regres-
sion, classification, or regression?
2.5 Survey more algorithms for ordinal regression in addition to those introduced
in this chapter.
2.6 What is the inherent loss function in the algorithm PRanking?
