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

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。

Within the latter circumstance, making use of a backport could possibly be impractical compared to upgrading to the newest Edition of the software.

Backporting is every time a software package patch or update is taken from a recent program Model and placed on an older Variation of a similar software package.

As mentioned within our Python web site submit, Just about every backport can generate numerous undesirable Unwanted effects within the IT environment.

偏导数是多元函数中对单一变量求导的结果，它在神经网络反向传播中用于量化损失函数随参数变化的敏感度，从而指导参数优化。

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

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。

利用计算得到的误差梯度，可以进一步计算每个权重和偏置参数对于损失函数的梯度。
