It corresponds to Kendall's τ, which measures the correlation between two rankings. Margin The margin loss returns the number of positions between the worst.

This paper presents a new criterion, PRO LOSS, concerning the prediction on all labels as well as the rankings of only relevant labels, and proposes ProSVM ...

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 y y (which is a 2D Tensor of target class indices).

Jun 26, 2019 · 前言 MultiLabelSoftMarginLoss损失函数，多标签分类损失。 很多文章都有介绍这个函数，他们给出的公式是： 但是我通过这个公式计算的值总是与直接引用损失函数计算的值不同，后来我把log换成了ln，结果就一致了。

Abstract Multilabel classification (ML) aims to assign a set of labels to an instance. This generalization of multiclass classification yields to the ...

If you know that for each example you only have 1 of 10 possible classes, you should be using CrossEntropyLoss , to which you pass your ...

The typical approach is to use BCEwithlogits loss or multi label soft margin loss. But what if the problem is now switched to all the labels ...

15.03.2018 · MultiLabelSoftMargin’s fomula is also same wi… 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.

MultiLabelSoftMarginLoss (weight=None, size_average=None, reduce=None, ... Creates a criterion that optimizes a multi-label one-versus-all loss based on ...

24.11.2019 · The loss you're looking at is designed for situations where each example can belong to multiple classes (say a person can be classified as both female and old). I think it's this "multi" that confuses you - it stands for the multiple possible classifications per example , not just multiple potential labels in the whole "universe".

Improving docs for MultiLabelSoftMarginLoss #15863 ... https://discuss.pytorch.org/t/multi-label-classification-in-pytorch/905 ...

The figure shows that both hyperparameters result in a smooth change of loss value, which makes it convenient to adjust hyperparameters and the ...

For all models, we tested both multi label margin loss as well as multi label soft margin loss. While we used a learning rate scheduler (PyTorch ...

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) . For each sample in the minibatch:

Jun 20, 2021 · MultiLabelSoftMarginLoss针对multi-label one-versus-all（多分类，且每个样本只能属于一个类）的情形。 loss的计算公式如下： 其中，x是模型预测的标签，x的shape是（N,C），N表示batch size，C是分类数；y是真实标签，shape也是（N,C），。 的值域是(0,）； 的值域是(1,）； 的 ...

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

Multilabel soft margin loss (implemented in PyTorch as nn.MultiLabelSoftMarginLoss ) can be used for this purpose. Here is an example with ...
