C.Intra-class Balancing(IntraCB) DUBE的类内平衡是通过基于预测误差为每个实例分配不同的采样概率实现的。对于输入 x 的标签空间 \mathcal{Y}:\lbrace c_1,c_2,...,c_m\rbrace ,给定分类器 f(·) 估计概率是 f(x)=\textbf{p}=[p_1,p_2,...,p_m]^\top 。对于label的 y=c_i定义onehot向...
而 intra-class imbalance 多出现于计算机视觉问题中,其解决方法通常是在 gradient update时,依据不同数据的难易程度进行 reweighting。另外一个常用的训练技巧就是 ensembling,即训练几个独立的模型再通过取平均值或者投票选class 来进行整合,作者们的DuBE也用到了 ensembling。与此同时,作者们致力于在训练的过程中将...
