TL;DR

  • I read this because.. : trick I used in #57
  • task : long-tail image classification
  • problem : In the real-world, classes are often unbalanced
  • idea : logit adjustment based on label frequency
  • architecture : ResNet-32, ResNet-50
  • objective : Add the values that go into the exponential of softmax plus the frequency per class multiplied by $\tau$.
  • baseline : ERM, weight normalisation, Adaptive, Equalized
  • data : CIFAR-10-LT, CIFAR-100-LT, ImageNet-LT, iNaturalist2018
  • evaluation : balanced error(average by class)
  • result : outperform baselines
  • limitation / things I cannot understand : Reading, but not understanding formulas and logic
