WebLong-tailed classiﬁcation. For the long-tailed classiﬁ-cation task, there is a rich body of widely used meth-ods including data re-sampling [3] and re-weighting [2,7]. Recent works [19,48] reveal the effectiveness of using different sampling schemes in decoupled training stages. Instance-balanced sampling is found useful for the ﬁrst fea ... WebAs the class size grows, maintaining a balanced dataset across many classes is challenging because the data are long-tailed in nature; it is even impossible when the sample-of-interest co-exists with each other in one collectable unit, e.g., multiple visual instances in one image.
