Focal loss in keras
WebMar 6, 2024 · Identity loss是指在计算机视觉中常见的一种损失函数,用于计算模型预测的输出和真实标签之间的差异。这个损失函数通常用于二分类或多分类问题,其中输出是一个概率分布。Identity loss的计算公式通常是输出和真实标签的交叉熵。 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. Unlike Softmax loss it is ...
