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。
com empowers brand names to thrive in a very dynamic marketplace. Their customer-centric strategy makes certain that each individual method is aligned with organization aims, providing measurable impression and very long-term good results.
In lots of situations, the consumer maintains the older Model in the software because the newer Edition has balance issues or can be incompatible with downstream programs.
Backporting is a common approach to address a known bug throughout the IT surroundings. Simultaneously, counting on a legacy codebase introduces other most likely sizeable stability implications for corporations. Depending on previous or legacy code could cause introducing weaknesses or vulnerabilities as part of your environment.

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。
通过链式法则，我们可以从输出层开始，逐层向前计算每个参数的梯度，这种逐层计算的方式避免了重复计算，提高了梯度计算的效率。
Backporting is often a capture-all phrase for almost any action that applies updates or patches from a more moderen Edition of software program to an more mature version.
Backporting has a lot of rewards, even though it truly is on no account a simple take care of to advanced security complications. Even more, depending on a backport inside the extensive-term may possibly introduce other stability threats, the risk of which may outweigh that of the original challenge.
Backports is usually a highly effective way to address safety flaws and vulnerabilities in older variations of software. Nonetheless, Each and every backport introduces a fair level of complexity inside the program architecture and may be pricey to maintain.
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。
链式法则是微积分中的一个基本定理，用于计算复合函数的导数。如果一个函数是由多个函数复合而成，那么该复合函数的导数可以通过各个简单函数导数的乘积来计算。
Backporting may give consumers a Fake sense of security In case the enumeration process is just not fully recognized. As an example, end users may perhaps read through media studies about upgrading their computer software to handle protection concerns. Having said that, what they actually do is install an up to date offer from the vendor instead of the newest back pr upstream Edition of the appliance.
