initialization list

先看几个常规的初始化：以上都为常规初始化，即调用类的构造函数进行初始化。 initialization list，即用初始化列表进行初始化，打破了原有的初始化格局，令初始化更加直观：这种方式的构造大体如下:

如何在ISE中调用Block Memory Generator实现rom？

paddlepaddle使用多进程报错“(External) CUDA error(3), initialization error.”的解决方法

使用paddlepaddle训练模型时，存在模型训练已结束，但GPU显存依然占用，影响下一次训练的问题。为了能够在模型训练结束后自动释放GPU显存，参考Tensorflow借助多进程释放内存的方法，可以将paddlepaddle的模型训练放到多进程中进行，从而让训练进程结束后GPU资源自动的释放。但是在使用 mult

神经网络的初始化方法总结 | 又名“如何选择合适的初始化方法”

前言本文介绍了为什么初始化很重要，总结了常用的几种初始化方法：全零或等值初始化、正态初始化、均匀初始化、Xavier初始化、He初始化和Pre-trained初始化，并介绍了几个还活跃的初始化方向：数据相关初始化、稀疏权重矩阵和随机正交矩阵初始化。为什么初始化很重要不正
