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。
算法从输出层开始，根据损失函数计算输出层的误差，然后将误差信息反向传播到隐藏层，逐层计算每个神经元的误差梯度。
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。
In several conditions, the user maintains the older Edition of your software program since the newer Edition has balance difficulties or might be incompatible with downstream applications.

The Poisonous Remarks Classifier is a strong device Studying Software applied in C++ designed to establish toxic reviews in electronic conversations.
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 numerous pros, nevertheless it truly is certainly not backpr site a simple deal with to complicated stability issues. Even further, relying on a backport within the very long-phrase may well introduce other security threats, the risk of which may outweigh that of the original challenge.
Backports may be a highly effective way to handle security flaws and vulnerabilities in more mature versions of application. On the other hand, Each individual backport introduces a fair amount of complexity within the method architecture and will be highly-priced to keep up.

参数偏导数：在计算了输出层和隐藏层的偏导数之后，我们需要进一步计算损失函数相对于网络参数的偏导数，即权重和偏置的偏导数。
Backporting can give users a Wrong sense of protection When the enumeration process is not really thoroughly recognized. One example is, users may perhaps read media studies about upgrading their application to deal with security troubles. Even so, what they really do is put in an current offer from The seller and not the newest upstream Variation of the applying.
