This paper was facing a task for binary classification, however there are other tasks need multiple class classification. There wer...
For algorithms that support multiclass classification (that is, K≥ 3): yj* is a vector of K –1 zeros, with 1 in the position corresponding to the true, observed class yj. For example, if the true class of the second observation is the third class and K = 4, then y2* = [0 ...
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 ...
Let's explore cross-entropy functions in detail and discuss their applications in machine learning, particularly for classification issues.
这就是最近很多人在研究的两类和多类损失函数的设计,关于这个主题可以参考"On the Design of Loss Functions for Classification"及Savage有篇老文章“Elicition of Personal Probabilities”,最近有一篇关于多类问题的引申,可以看"composite multiclass loss"。
We also propose a robust loss function against outliers in multiclass classification based on our approach. The robust loss function is a natural extension of the existing robust loss function for binary classification. A model of mislabeling and a robust loss function are useful to cope with ...
