Loss functionsClassificationIncorporating higher-order optimization functions, such as Levenberg-Marquardt (LM) have revealed better generalizable solutions for deep learning problems. However, these higher-orde
Each trainer supports only a subset of the losses mentioned above. To get the supported losses and the default loss, please refer to the documentation page for the specific trainer. TheHinge lossfor classification. Its string name is'hinge'. ...

尽管SVM 常常被采用 1 v all 或者 1v1 的方式扩展到multiclass classification中[2],事实上还有一种“真正的”多类 Hinge loss 版本,由Crammer and Singer,[3]提出, 在[4]中给出定义了。 在结构化推断structured prediction中,hinge loss 可以被更远地扩展到结构话输出空间上。采用下面的变体的间隔重形变技术...
In this study, the applicability of hinge loss and LM to classification problems is analyzed. In this paper, the Hinge loss function is converted to the squared multiclass Hinge loss function, with l2-regularization added to it. All the MSE options and new forms of the multiclass squared hin...

While CNN models are typically trained with category label supervision and softmax loss for product image retrieval, we propose a different approach for feature extraction using the squared-hinge loss, an alternative multiclass classification loss function. First, transfer learning is performed on a ...
Finally, we develop multicategory large margin classification methods by using a so-called multiclass C-loss.doi:10.1016/j.artint.2014.06.002Zhihua ZhangKey Laboratory of Shanghai Education Commission for Intelligence Interaction & Cognition EngineeringCheng Chen...
