New loss reweighting method targets imbalance learning via Neural Collapse

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.

    Rethinking Loss Reweighting for Imbalance Learning as an Inverse Problem: A Neural Collapse Point of View

    Loss reweighting is a widely used strategy for long-tailed classification, but existing reweighting strategies often rely on heuristics and rarely define a well-specified target. Inspired by Neural Collapse (NC), the ideal simplex Equiangular Tight Frame (ETF) terminal geometry s…
