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。
This method is often as easy as updating various lines of code; it also can entail A serious overhaul which is spread across many data files of your code.
com empowers brands to thrive in a very dynamic Market. Their shopper-centric method makes certain that just about every tactic is aligned with enterprise ambitions, offering measurable influence and prolonged-time period success.
隐藏层偏导数：使用链式法则，将输出层的偏导数向后传播到隐藏层。对于隐藏层中的每个神经元，计算其输出相对于下一层神经元输入的偏导数，并与下一层传回的偏导数相乘，累积得到该神经元对损失函数的总偏导数。
Increase this site Add a description, picture, and links for the backpr subject webpage in order that developers can much more very easily find out about it. Curate this matter
Within this scenario, the person continues to be functioning an older upstream Variation with the software with backport offers utilized. This does not provide the full security measures and advantages of working the latest Variation on the application. Users should double-Check out to check out the precise software program update variety to ensure They may be updating to the most recent Model.
Figure out what patches, updates or modifications can Back PR be obtained to address this concern in afterwards versions of a similar computer software.
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。
的原理及实现过程进行说明，通俗易懂，适合新手学习，附源码及实验数据集。
Backporting has several pros, even though it really is certainly not a straightforward correct to sophisticated stability difficulties. Further, counting on a backport during the prolonged-time period might introduce other safety threats, the chance of which can outweigh that of the initial difficulty.
Backports might be a successful way to handle protection flaws and vulnerabilities in older variations of program. However, each backport introduces a good volume of complexity inside the method architecture and will be high priced to maintain.

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。
根据问题的类型，输出层可以直接输出这些值（回归问题），或者通过激活函数（如softmax）转换为概率分布（分类问题）。
