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...

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...

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...

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, ...
To revert to the Visual Studio .NET behavior for types initialized inside of a constructor's initialization list, remove initialization from the list as follows. Copy class C { T t; int i; public: C() {} // Members of class are not initialized. }; ...
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 ...
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...
