A new research paper explores the effectiveness of fine-grained training in classification tasks, particularly when dealing with hierarchical labels. The study, published on arXiv, indicates that while fine-grained training can improve performance, its success is not universal and depends on the geometric structure of the data and its relationship with the label hierarchy. Key factors influencing this benefit include the alignment between decision boundaries for fine- and coarse-grained tasks, dataset size, model capacity, and the degree of overparameterization. AI
