SHANGHAI, Jan. 22 (Xinhua) -- Ruan Weiguo, a physical education teacher of the East China University of Political Science and Law in Shanghai, decided to launch a weight loss class for the upcoming semester in March. Students attending the class can earn two academic credits, and at the ...
在class-balanced loss中,每个类别的损失权重与其样本数量成反比,即样本数量越多的类别,其损失权重越小,样本数量越少的类别,其损失权重越大。这样做的好处是可以更加注重对少数类别的学习,从而提高模型在少数类别上的表现。相比于传统的交叉熵损失函数,class-balanced loss能够更好地处理类别不平衡问题,提高模型在整个...
