计算机并不随机。相反,硬件设计师非常努力地确保计算机每次都以相同的方式运行每个程序。因此,当一个程序确实需要随机数时,那就需要付出额外的努力。传统上,计算机科学家和编程语言区分了两种不同的随机数:统计随机性和加密随机性。在Go中,它们分别由math/rand和crypto/rand提供。这篇文章是关于Go 1.22如何通过在math/rand(以及我们之前文章中提到的math/rand/v2)中使用加密随机数源,使这两者更加靠近。结果是更好的随机性和在开发人员意外地使用math/rand代替crypto/rand时所带来的损失大大减少。
这是有关 对象管理 的系列教程中的第七篇。它为形状增加了一些行为,并可以针对每个生成区域配置它们。
2.4.1: Simulating Randomness 模拟随机性 Many processes in nature involve randomness in one form or another investigate the motions of microscopic molecules or study the popularity of electoral candidates,we see randomness , or at least apparent randomness, almost everywhere. In addition to phenomena that are genuinely random,we often use randomness when modeling complicated put this differently, we model what we can,and whatever it happens to be left out, we attribute to randomness

For better efficiency and randomness, create a single Random, then store, and reuse it. 对应的接口包括 void add_device_randomness(const void *buf, unsigned int size); void add_input_randomness(unsigned int type, unsigned int code, unsigned int value); void add_interrupt_randomness(int irq, int irq_flags ); void add_disk_randomness(struct gendisk *disk); 内核提供了 1 个的接口来供其他内核模块使用。

我们将使用frame_support 中的Randomness trait执行此操作。它将能够生成一个随机的种子,我们将用它来创建独特的小猫,并培育新的小猫。 在pallet的配置特征中,定义受Randomness特征约束的新类型。来自frame_support中Randomnesstrait 需要使用参数来指定Output和BlockNumber泛型。 将 ACTION #5 行替换为:type KittyRandomness: Randomness<Self::Hash, Self::BlockNumber>;在runtime中指定实际类型。 Balances; type KittyRandomness = RandomnessCollectiveFlip; // <-- ACTION: add this line.}在这里,我们从其接口(Randomness
从引入randomness的角度来看,SGD中计算的梯度是对original-loss梯度的近似,相当于在original-loss梯度的基础上加了randomness,因此即使当前走到了original-loss 的奇点,SGD计算的梯度因为引入了randomness,所以也不接近0,比较容易跳出奇点。 而SGD每次走的方向是minibatch-loss的负梯度方向(或者理解成original-loss的负梯度+randomness),显然这个方向和original-loss的负梯度方向不同,也就不是original-loss
