参数的过程中使用的一种求导法则。 具体来说，链式法则是将复合函数的导数表示为各个子函数导数的连乘积的一种方法。在

在神经网络中，损失函数通常是一个复合函数，由多个层的输出和激活函数组合而成。链式法则允许我们将这个复杂的复合函数的梯度计算分解为一系列简单的局部梯度计算，从而简化了梯度计算的过程。
Backporting is every time a program patch or update is taken from a new computer software Model and placed on an older version of the identical software program.
中，每个神经元都可以看作是一个函数，它接受若干输入，经过一些运算后产生一个输出。因此，整个
Equally as an upstream software package application impacts all downstream purposes, so way too does a backport placed on the Main software. This is certainly also accurate In case the backport is applied in the kernel.
CrowdStrike’s knowledge science staff confronted this exact dilemma. This information explores the group’s decision-making system plus the steps the staff took to update approximately 200K lines of Python into a contemporary framework.

偏导数是指在多元函数中，对其中一个变量求导，而将其余变量视为常数的导数。
Conduct sturdy testing to make certain that the backported code or backport package maintains whole functionality inside the IT architecture, and also addresses the fundamental safety flaw.
