初始化系列之零初始化(zero initialization) 零初始化 把一个对象的初始化值设置为0 说明 零初始化会在下面的情况下执行: 对于任何static或者thread-local变量,没有使用const,在任何初始化之前,会进行0初始化,也就是static和thread-local修饰的变量会0初始化 如果不是类,作为数值初始化序列的一部分;如果是类,并且...
初始化系列之零初始化（zeroinitialization）零初始化 把⼀个对象的初始化值设置为0 说明 零初始化会在下⾯的情况下执⾏：1. 对于任何static或者thread-local变量，没有使⽤const，在任何初始化之前，会进⾏0初始化，也就是static和thread-local修饰的变量会0 初始化 2. 如果不是类，作为数值初始化序列...
那么很自然的,便是将神经网络的权重层初始化为一个单位矩阵,这种初始化方法被称为恒等初始化(Identity Initialization)。在理论上恒等初始化具有相当好的性质,这种性质被称为动力等距(Dynamical Isometry),最早由 Saxe 等人在2014年提出,它描述了当输入输出的雅可比矩阵的奇异值分布全部在 1 附近时,即 (这里 表示输出...
The effects of zero-initialization are: IfTis ascalar type, the object is initialized to the value obtained byexplicitly convertingthe integer literal0(zero) toT. IfTis a non-union class type: allpadding bitsare initialized to zero bits, ...
下面的代码可以说明一切: 默认情况下模板内的基本类型(int float ...)是不会自动初始化为0的(不像一般函数/类中),要想实现其自动初始化可以在模板函数中T x = T(); 在类中可以在构造函数列表中: x(), y()... #include<iostream>usingnamespacestd;template<typenameT>voidf(constT&){//T x = T...
ZerO Initialization: Initializing Neural Networks with only Zeros and Ones 论文链接: https://openreview.net/pdf?id=1AxQpKmiTc 1 『从恒等初始化开始』 困扰随机初始化方法的很关键的一点在于如何使得神经网络各层参数之间的方差不发生变化,那么一种简单的...
We are migrating some VAX FORTRAN applications that exploit the default zero initialization that the VAX (but not AXP!) did for scalars and, I believe, arrays along with the implicit SAVE. Until the explicit initializations can be added we need to emulate the VAX behavior as closely as ...
C++ Zero-Initialization Ask Question Asked6 years, 8 months ago Modified5 years ago Viewed19k times 32 I'm having trouble understanding when and why exactly a member in my class is zero-initialized according tohttp://en.cppreference.com/w/cpp/language/zero_initialization....
In other words, when I got garbage values, my defaulted default constructor was indeed user-provided since it was not explicitly efaulted on its first declaration. Therefore, what happened was not zero initialization but default initialization. Thanks @Columbo again for pointing out the real pr...
