WebWarmup and Decay是模型训练过程中，一种学习率（learning rate）的调整策略。. Warmup是在ResNet论文中提到的一种学习率预热的方法，它在训练开始的时候先选择使用一个较小的学习率，训练了一些epoches或者steps (比如4个epoches,10000steps),再修改为预先设置的学习来进行 ... WebGenerally, during semantic segmentation with a pretrained backbone, the backbone and the decoder have different learning rates. Encoder usually employs 10x lower learning rate when compare to decoder. To adapt to this condition, this repository provides a cosine annealing with warmup scheduler adapted from katsura-jp. The original repo ...
