step1:首先定义和gj为 step2:逐层求导: 第1、2、3层: 第4、5层: step3:求出代价函数关于步长的导数: step4:确定步长: 如图(2)和图(3)所示,步长的确定分为两种情况: 情况一: 情况二: step5:判断选取步长是否超过最大允许范围,若超过范围,则令α(q):=αmax 步骤5:利用梯度和所选步长调整模型参
Fast Adversarial Training with Adaptive Step Size 论文链接: https://arxiv.org/abs/2206.02417 背景知识 FreeAT 首先提出了一种快速对抗训练的方法,通过批量重复训练并同时优化模型参数和对抗扰动。YOPO 采用了类似的策略来优化对抗损失函数。后来,单步法被证明比 FreeAT 和 YOPO 更有效。如果仔细调整超参数,带随机...

RT @SeunghyunSEO7 The concept of critical batch size is quite simple. Let’s assume we have a training dataset with 1M tokens. If we use a batch size of 10, we can update model param 100,000 times. On the other hand, if we increase the batch size to 100, the step size decreases...
