In machine learning and computer vision fields, a wide range of applications, such as human age estimation and head pose recognition, are related to ordinal data in which there exists an order relationship. To perform such ordinal estimations in a desired metric space, in this paper we first propose a novelordinal margin metric learning(ORMML) method by separating the data classes with a sequence of margins, which makes the classes distribute orderly in the learned metric space. Then, to cope with more realistic scenarios where the data are sampled with each class across multiple distributions, we present a cross-distribution variant of ORMML, coined as CD-ORMML, by maximizing the correlation between distributions within each class when conducting metric learning. Finally, extensive experiments on synthetic and publicly available image datasets demonstrate the superiority of the proposed methods in performance to the state-of-the-art methods.
