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

前向传播是神经网络通过层级结构和参数，将输入数据逐步转换为预测结果的过程，实现输入与输出之间的复杂映射。

was the final Formal release of Python two. As a way to continue being current with stability patches and keep on enjoying all of the new developments Python has to offer, corporations needed to improve to Python 3 or start out freezing needs and decide to legacy prolonged-expression assistance.

Equally as an upstream program software affects all downstream applications, so far too does a backport applied to the core software. This can be also real If your backport is used inside the kernel.

Ascertain what patches, updates or modifications can be obtained to address this problem in afterwards versions of exactly the same software program.

Backporting involves access to the computer software’s source code. As such, the backport can be made and supplied by the Main enhancement workforce for closed-supply software package.

On the other hand, in decide on instances, it might be required to keep a legacy software When the newer Variation of the application has security problems that will influence mission-important functions.

Backports is BackPR often an efficient way to deal with safety flaws and vulnerabilities in older variations of computer software. Even so, Each and every backport introduces a good level of complexity throughout the system architecture and may be pricey to keep up.

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）。
