网络的权重和偏置如下（这些值是随机初始化的，实际情况中会使用随机初始化）：
反向传播算法利用链式法则，通过从输出层向输入层逐层计算误差梯度，高效求解神经网络参数的偏导数，以实现网络参数的优化和损失函数的最小化。
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。

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。
Carry out strong screening to make sure that the backported code or backport package maintains entire performance inside the IT architecture, and also addresses the underlying stability flaw.
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。
Backporting can give customers a false perception of stability Should the enumeration course of action just isn't thoroughly understood. By way of example, users may perhaps study media experiences about upgrading their computer software to address stability challenges. Even so, what they really do is set up an updated package deal from The seller and never the newest upstream Model of the applying.
