Researchers have introduced REPAIR, a novel framework for long-tailed reranking designed to improve model performance on classification tasks with imbalanced datasets. Unlike previous methods that apply fixed offsets to model logits, REPAIR decomposes the necessary correction into classwise and pairwise components. This decomposition allows for more adaptive adjustments, particularly when the relative ranking of classes varies across different inputs. Experiments across nine benchmarks, including text classification and visual recognition, demonstrate REPAIR's effectiveness in scenarios where pairwise correction is beneficial. AI
