YOLO .cfg文件中的比例和步长值是什么意思? [英] What does scale and step values in .cfg file of YOLO means?

问题描述

我正在尝试了解YOLOv2的.cfg文件.我不明白

I am trying to understand the .cfg file of YOLOv2. I didn't understand

steps = -1,100,80000,100000

steps=-1,100,80000,100000

scales = .1,10，.1，.1

scales=.1,10,.1,.1

有人可以给我解释一下吗

Can someone explain me this.

推荐答案

步骤是将应用比例的检查点(迭代次数).

steps is a checkpoints (number of iterations) at which scales will be applied.

scales 是在此检查点乘以 learning_rate 的系数.确定在训练期间不断增加迭代次数时，如何更改 learning_rate .

scales is a coefficients at which learning_rate will be multiplied at this checkpoints. Determines how the learning_rate will be changed during increasing number of iterations during training.

它们两者相互关联，并且数量相同.

Both of them are related to each other and they have the same amount.

steps=200,400,600,20000,30000

scales=2.5,2,2,.1,.1

在步骤200，比例为2.5，在步骤400，比例为2，依此类推.

At step 200 the scales is 2.5, step 400 the scale is 2, etc.
