This paper was facing a task for binary classification, however there are other tasks need multiple class classification. There wer...
The paper proposes a new loss function for multiclass, single-label classification. Experiments were conducted with convolutional neural networks trained on several popular data sets. Tests with multilayer perceptron were also carried out. The obtained results indicate that the proposed loss may be a ...
