Abstract:

Multi-target models are machine learning models that simultaneously predict several target attributes. Due to a high number of real-world applications, the field of multi-target prediction is actively developing. With the growing number of multi-target techniques, there is a need for comparing them among each other. However, while established procedures exist for comparing conventional, single-target models, little research has been done on making such comparisons in the presence of multiple targets. In this paper, we highlight the challenges of evaluating multi-target models, focusing on multi-target regression algorithms. This paper reviews the common practice and discusses its shortcomings, indicating directions for future research.
