根据 #2951 新增两个 ratio2weight 函数。代码里延续论文中的命名,所以原
ratios2weight
改为ratios2weight_1
。Type 3 示例:
Type 2/1 示例:
但是 https://github.com/PaddlePaddle/PaddleClas/blob/release/2.5/ppcls/loss/dmlloss.py 中 import 了
ratio2weight
这个函数,目前的解决方案是在 dmlloss 中开启 weight_type 和 weight_alpha 这两个参数,与 multilabelloss 中保持一致,然后计算对应的 loss。
