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）：

This process can be as easy as updating many traces of code; it can also include A significant overhaul that is definitely spread throughout multiple documents of your code.

While in the latter circumstance, making use of a backport can be impractical when compared with upgrading to the latest version with the computer software.

Backporting is often a multi-move system. In this article we define the basic actions to build and deploy a backport:

Backporting is a common system to handle a identified bug inside the IT environment. At the same time, depending on a legacy codebase introduces other possibly important protection implications for organizations. Relying on old or legacy code could result in introducing weaknesses or vulnerabilities in your surroundings.

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

Even so, in pick out instances, it may be required to keep a legacy application When the more recent Variation of the applying has steadiness troubles which will impact mission-important functions.

Backporting has lots of positive aspects, although it truly is certainly not an easy correct to backpr site intricate safety issues. Even more, relying on a backport during the extensive-time period may introduce other stability threats, the chance of which can outweigh that of the original challenge.

It is possible to terminate at any time. The helpful cancellation date are going to be for the forthcoming thirty day period; we can't refund any credits for The present month.

根据计算得到的梯度信息，使用梯度下降或其他优化算法来更新网络中的权重和偏置参数，以最小化损失函数。

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。
