注意到Xavier初始化是基于Linear推出的,但是一个只有Linear的神经网络无法拟合非线性的函数,因此我们要考虑非线性的激活函数带来的影响。 He initialization,即方差2/n初始化就是考虑了Relu后的初始化方法。 让我们回到式(1),假设我们latent输出在过了Linear之后,又过了一层Relu,才得到输出Y,假设总是有p(0=<p<=1...
针对于Relu的激活函数,基本使用He initialization,pytorch也是使用kaiming 初始化卷积层参数的。

Kaiming (He) Weight Initialization - Deep Learning Dictionary Before training a network, we can initialize our weights from a number of different weight initialization techniques. As we've previously learned, the exact way in which the weights are initialized can impact the training process. Cert...

电脑重装系统后,什么都没有了,重装部分必须用的软件后,不管是在桌面还是在文件夹中,当点击鼠标右键时,总是弹出错误,如下图所示: 上网找解决方法,也没有找到,但是看错误,是与SVN有关。 产生原因:TortoiseSVN没有安装在C盘 解决方法:卸载重装到C盘,路径直接默认不用修改。
