Mar 15, 2018 · I think there is no difference between BCEWithLogitsLoss and MultiLabelSoftMarginLoss. BCEWithLogitsLoss = One Sigmoid Layer + BCELoss (solved numerically unstable problem) MultiLabelSoftMargin’s fomula is also same with BCEWithLogitsLoss. One difference is BCEWithLogitsLoss has a ‘weight’ parameter, MultiLabelSoftMarginLoss no has)

MultiLabelSoftMarginLoss — PyTorch 1.10.0 documentation MultiLabelSoftMarginLoss class torch.nn.MultiLabelSoftMarginLoss(weight=None, size_average=None, reduce=None, reduction='mean') [source] Creates a criterion that optimizes a multi-label one-versus-all loss based on max-entropy, between input x x and target y y of size (N, C) (N,C) .

MultiLabelMarginLoss — PyTorch 1.10.1 documentation MultiLabelMarginLoss class torch.nn.MultiLabelMarginLoss(size_average=None, reduce=None, reduction='mean') [source] Creates a criterion that optimizes a multi-class multi-classification hinge loss (margin-based loss) between input x x (a 2D mini-batch Tensor ) and output

MultiLabelSoftMarginLoss. class torch.nn. MultiLabelSoftMarginLoss (weight=None, size_average=None, reduce=None, reduction='mean')[source].

1、BCEloss是可以处理多标签的，官方文档BCEWithLogitsLoss中描述说"In the case of multi-label classification the loss can be described as:...". 2、按照PyTorch中文档的定义来说，两个函数是一致的，MultiLabelSoftMarginLoss就是BCEWithLogitsLoss中Losspos_weight=None的情形。 PS:两者在做reduce的时候计算顺序是略有区别的，会导致设置 ...

그래서 Multi Class Classification 문제를 풀 때는 torch.nn.CrossEntropyLoss를 사용한다. 그런데 pytorch를 사용하다보니 torch.nn.

15.03.2018 · my pytorch version is ‘0.3.0 post4’, this version doesn’t have a ‘reduce’ parameter in BCEWithLogitsLoss and MultiLabelSoftMarginLoss. Thank you for your reply again! ptrblck March 15, 2018, 11:51am

20.06.2021 · MultiLabelSoftMarginLoss不知道pytorch为什么起这个名字，看loss计算公式，并没有涉及到margin。 按照我的理解其实就是多标签交叉熵损失函数，验证之后也和BCEWithLogitsLoss的结果输出一致例子：import torchimport torch.nn.functional as Fimport torch.nn as nnimport mathdef validate_MultiLabelSoftMarginLoss(input, target)

Jun 06, 2021 · I am trying to understand how to use MultiLabelSoftMarginLoss and BCEWithLogitsLoss. my question is in two parts, for simplicity I consider the case of multi-lable classification for images. what should be the format for the targets? should it be 0 and 1 where 0 means that the input does not contain that category and 1 means that the input includes that category? why the minimum of neither of ...

Nov 25, 2019 · In pytorch 1.8.1, I think the right way to do is fill the front part of the target with labels and pad the rest part of the target with -1. It is the same as the MultiLabelMarginLoss, and I got that from the example of MultiLabelMarginLoss. Share answered Mar 29 '21 at 5:45 Orange Chen 1 1 Add a comment Your Answer Post Your Answer

同样，在模型训练完成后也可以通过上面的prediction函数来完成推理预测。需要注意的是，在TensorFlow 1.x中sigmoid_cross_entropy_with_logits方法返回的是所有样本损失的均值；而在Pytorch中，MultiLabelSoftMarginLoss默认返回的是所有样本损失的均值，但是可以通过指定参数reduction为mean或sum来指定返回的类型。
