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。
A backport is most often applied to handle security flaws in legacy software package or more mature versions on the software program that are still supported via the developer.
Backporting is each time a application patch or update is taken from a new software version and applied to an more mature Edition of the exact same software.
was the ultimate Formal launch of Python two. In an effort to remain present with stability patches and continue savoring each of the new developments Python has to offer, companies required to upgrade to Python 3 or commence freezing needs and decide to legacy very long-expression help.
Equally as an upstream software package application has an effect on all downstream apps, so far too does a backport applied to the Main application. That is also correct When the backport is used within 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。
Backporting involves entry to the software program’s supply code. Therefore, the backport might be created and provided by the core development workforce for closed-resource software program.

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。
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。
