WebFeb 12, 2024 · This paper focuses on changing Fock matrix elements of two-mode squeezed vacuum state (TMSVS) by employing three conditional operations in one-sided lossy channel. These three conditional operations include one-photon replacement (OPR), one-photon substraction (OPS) and one-photon addition (OPA). focal loss从样本难易分类角度出发，解决样本非平衡带来的模型训练问题。 相信很多人会在这里有一个疑问，样本难易分类角度怎么能够解决样本非平衡的问题，直觉上来讲样本非平衡造成的问题就是样本数少的类别分类难度较高。因此从样本难易分类角度出发，使得loss聚焦于难分样本，解决了样本少的类别分类准确率 … See more Focal loss是最初由何恺明提出的，最初用于图像领域解决数据不平衡造成的模型性能问题。本文试图从交叉熵损失函数出发，分析数据不平衡问题，focal loss与交叉熵损失函数的对比，给 … See more Loss = L(y, \hat{p})=-ylog(\hat{p})-(1-y)log(1-\hat{p}) 其中\hat{p}为预测概率大小。 y为label，在二分类中对应0，1。 L_{ce}(y, \hat{p}) = \begin{cases} -log(\hat{p}), & … See more 基于样本非平衡造成的损失函数倾斜，一个直观的做法就是在损失函数中添加权重因子，提高少数类别在损失函数中的权重，平衡损失函数的分布。如在上述二分类问题中，添加权重参数 … See more 对于所有样本，损失函数为： L=\frac{1}{N}\sum_{i=1}^N l(y_i, \hat{p}_i) 对于二分类问题，损失函数可以写为： L=\frac{1}{N}(\sum_{y_i =1}^m -log(\hat{p})+\sum_{y_i=0}^{n} … See more WebFock is a surname.
