WebFocal loss. focal loss with multi-label implemented in keras. reference to paper : Focal Loss for Dense Object Detection add LSR (label smoothing regularization) Usage. firstly, you should get a list which contains each class number, like classes_nu=[1,2,3] means index_0 class have 1 pic, index_1 class have 1 pics, index_2 class have 3 pics. WebFocal loss; Assigning weights to different loss; Initialization of the last layer; Training and Evaluation: We provide 3 .sh scripts for training and evaluation. On original CIFAR dataset:./cifar_trainval.sh On long-tailed CIFAR dataset (the hyperparameter IM_FACTOR is the inverse of "Imbalance Factor" in the paper):

WebDec 14, 2024 · If we use this loss, we will train a CNN to output a probability over the C classes for each image. It is used for multi-class classification. What you want is multi-label classification, so you will use Binary Cross-Entropy Loss or Sigmoid Cross-Entropy loss. It is a Sigmoid activation plus a Cross-Entropy loss.
