Hinge range loss
Webb8 aug. 2024 · First, for your code, besides changing predicted to new_predicted.You forgot to change the label for actual from $0$ to $-1$.. Also, when we use the sklean hinge_loss function, the prediction value can actually be a float, hence the function is not aware that you intend to map $0$ to $-1$.To achieve the same result, you should pass … Webb14 apr. 2015 · Hinge loss leads to better accuracy and some sparsity at the cost of much less sensitivity regarding probabilities.

WebbMeasures the loss given an input tensor x x x and a labels tensor y y y (containing 1 or -1). nn.MultiLabelMarginLoss. Creates a criterion that optimizes a multi-class multi-classification hinge loss (margin-based loss) between input x x x (a 2D mini-batch Tensor) and output y y y (which is a 2D Tensor of target class indices). nn.HuberLoss
Webb16 mars 2024 · Based on the definitions and properties of the two loss functions, we can draw several conclusions about their differences. Firstly, while both functions benefit from their convexity property, the logistic loss is smooth whereas the hinge loss isn’t. This makes the former more suitable for large-scale problems. WebbMulticlassHingeLoss ( num_classes, squared = False, multiclass_mode = 'crammer-singer', ignore_index = None, validate_args = True, ** kwargs) [source] Computes the mean Hinge loss typically used for Support Vector Machines (SVMs) for multiclass tasks. The metric can be computed in two ways. Either, the definition by Crammer and Singer is used ...
WebbHingeLoss主要用于SVM二分类,在SVM中用于多分类的话,通常是通过one vs one或者one vs all或者推广HingeLoss来实现. 尽管从原理上(就是网上到处可见的那个图)来说,HingeLoss、Exponential Loss、CE(Softmax)Loss是差不多的,但是用于NN多分类的话,只有CE Loss是最好用的 ...
