WebExisting long-tail image classification methods try to alleviate the head-tail imbalance majorly by re-balancing the data distribution, assigning the optimized weights, and augmenting information, but they often get in trouble with the trade-off on the head and tail performance which mainly caused by the poor representation learning of tail classes. WebExisting long-tailed classification (LT) methods only focus on tackling the class-wise imbalance that head classes have more samples than tail classes, but overlook the attribute-wise imbalance.In fact, even if the class is balanced, samples within each class may still be long-tailed due to the varying attributes. overwrite programs https://drumbeatinc.com
