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
This may be done as Component of an official patch or bug fix. For open-supply software, which include Linux, a backport can be provided by a 3rd party after which you can submitted to the software package enhancement staff.
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。
In lots of scenarios, the person maintains the older version of your software program since the more recent Edition has stability troubles or may be incompatible with downstream purposes.
Increase this website page Add an outline, picture, and one-way links to your backpr matter page making sure that developers can extra simply understand it. Curate this matter
With this situation, the user continues to be operating an older upstream Edition of the application with backport deals applied. backpr This does not deliver the full safety features and benefits of running the most up-to-date version on the application. Users really should double-Test to check out the precise computer software update variety to be certain They may be updating to the most recent Model.
You can cancel at any time. The productive cancellation date are going to be with the forthcoming thirty day period; we can not refund any credits for The existing month.

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。
在神经网络中，偏导数用于量化损失函数相对于模型参数（如权重和偏置）的变化率。
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。
