输出层偏导数：首先计算损失函数相对于输出层神经元输出的偏导数。这通常直接依赖于所选的损失函数。
This may be carried out as A part of an official patch or bug fix. For open-resource application, for example Linux, a backport is often supplied by a third party and then submitted to your software program progress group.
A backport is most commonly made use of to handle protection flaws in legacy software program or older versions from the program that remain supported by the developer.
In several conditions, the consumer maintains the older version of the software since the more recent Variation has security problems or may very well be incompatible with downstream applications.
Strengthen this page Include an outline, impression, and one-way links into the backpr subject web page to ensure developers can more easily study it. Curate this subject
Equally as an upstream application application has an effect on all downstream apps, so also does a backport placed on the core software program. This is also true Should the backport is applied throughout the kernel.
反向传播算法基于微积分中的链式法则，通过逐层计算梯度来求解神经网络中参数的偏导数。

Backporting has quite a few rewards, although it is not at all an easy fix to advanced safety problems. Even further, relying on a backport while in the long-phrase may well introduce other stability threats, the risk of which may outweigh that of the original situation.
过程中，我们需要计算每个神经元函数对误差的导数，从而确定每个参数对误差的贡献，并利用梯度下降等优化
的基础了，但是很多人在学的时候总是会遇到一些问题，或者看到大篇的公式觉得好像很难就退缩了，其实不难，就是一个链式求导法则反复用。如果不想看公式，可以直接把数值带进去，实际的计算一下，体会一下这个过程之后再来推导公式，这样就会觉得很容易了。
在神经网络中，偏导数用于量化损失函数相对于模型参数（如权重和偏置）的变化率。
These concerns impact not merely the leading software but in addition all dependent libraries and forked programs to public repositories. It is vital to take backpr into account how Just about every backport matches inside the Business’s overall protection approach, and also the IT architecture. This applies to both upstream software package programs and the kernel itself.
