Generalized Kullback-Leibler Divergence Loss

广义Kullback-Leibler散度损失

Jiequan Cui, Beier Zhu, Qingshan Xu, Zhuotao Tian, Xiaojuan Qi, Bei Yu, Hanwang Zhang, Richang Hong

机构 * Hefei University of Technology(合肥工业大学) University of Science and Technology of China(中国科学技术大学) Nanyang Technological University(南洋理工大学) The Chinese University of Hong Kong(香港中文大学) The University of Hong Kong(香港大学) Harbin Institute of Technology, Shenzhen(哈尔滨工业大学(深圳))

AI总结 本文提出广义KL散度损失,通过解耦KL损失为加权MSE和交叉熵损失,并引入非对称优化修正和类别全局信息,在对抗训练和知识蒸馏中取得SOTA性能。
