https://github.com/shuxinyin/NLP-Loss-Pytorch 数据不均衡问题也可以说是一个长尾问题,但长尾那部分数据往往是重要且不能被忽略的,它不仅仅是分类标签下样本数量的不平衡,实质上也是难易样本的不平衡。 解决不均衡问题一般从两方面入手: 数据层面:重采样,使得参与迭代计算的数据是均衡的; ...

DiceLoss ohem 总结: PSENet是文本检测网络。 GitHub - whai362/PSENet: Official Pytorch implementations of PSENet. 首先我想说一句,这个PSENet写的模块,代码都非常好,非常值得学习。 每一部分: backbone + neck + head + post_precessing + loss 摘要 目前的文本检测有2个挑战: 1)基于anchor检测的方法,对任意...
(2)Dice Loss比较适用于样本极度不均的情况,一般的情况下,使用 Dice Loss 会对反向传播造成不利的影响,容易使训练变得不稳定。 所以在一般情况下,还是使用交叉熵损失函数。 PyTorch参考代码 import torch.nn as nn import torch.nn.functional as F
1 dice loss 骰子系数或Sørensen-Dice系数,是一种常见的标准二进制分类任务,如像素分割,也可以修改作为损失函数: #PyTorch classDiceLoss(nn.Module): def__init__(self,weight=None,size_average=True): super(DiceLoss,self).__init__() defforward(self,inputs,targets,smooth=1): ...
