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。

com empowers brand names to prosper in the dynamic Market. Their consumer-centric method makes certain that just about every method is aligned with organization goals, providing measurable effects and prolonged-time period accomplishment.

Backporting is any time a software package patch or update is taken from the latest software package Variation and placed on an more mature Model of the identical computer software.

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

Just as an upstream application software affects all downstream apps, so too does a backport placed on the core program. This is often also true If back pr your backport is applied inside the kernel.

反向传播的目标是计算损失函数相对于每个参数的偏导数，以便使用优化算法（如梯度下降）来更新参数。

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。
