Researchers have proposed a new approach to loss reweighting for imbalanced classification problems, drawing inspiration from Neural Collapse theory. This method views loss reweighting as an inverse problem, dynamically inferring class weights to achieve an ideal objective of equal per-class average loss. Empirical results indicate that this inverse-view reweighting strategy effectively reduces loss imbalance and aligns better with Neural Collapse geometry, outperforming existing long-tailed classification baselines.
