对于训练过程里的代码有个疑问150~161 #3

请参考文章关于更新MW-Net参数的数学表达式。 |
|
@xjtushujun @jingzhengli 您好,我也是看到这个地方,有些不理解。meta_model 本身是不包含vnet的,vnet的梯度是怎么计算出来的呢?我发现meta_model.update_params这行代码应该很重要,我去掉这行,vnet的梯度就不能计算了。可是这行代码调用的函数 只和meta_model相关,是怎么能和vnet有联系的呢?如果方便 麻烦讲解一下,谢谢您! |
It's related to the update_params() method defined in MetaModule class in resnet.py. |
关于网络参数更新的问题想请教一下, |
same problem, can anyone explain this? I understand all the math in the paper, but I dont understand the code for gradient calculation. |
optimizer_c中优化的是vnet的参数,但是损失l_g_meta中我没有看到vnet网络的参与,我有点想不清楚网络是如何迭代的
