Ohem ratio
Webb例如，在ssd和ohem中，只有很小一部分样本(损失值最大的样本)的梯度会被反向传播。 在RefineDet中，一个anchor refinement module用来过滤容易的负样本。 另一种改进是设计新的损失函数，通过重新定义标准的交叉熵损失，使其更关注于困难的、分类错误的样本（比如RetinaNet中提出的Focal Loss）。 WebbLOINC. One milliliter of whole blood was incubated for 1624 h at 37C, after which plasma was harvested and tested using an enzyme-linked immunosorbent assay for the presence of IFN- produced in response to the peptide antigens or PHA (mitogen).
