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 can be accomplished as Element of an official patch or bug repair. For open-resource computer software, such as Linux, a backport could be supplied by a 3rd party and after that submitted to your software program progress workforce.
Inside the latter case, making use of a backport could possibly be impractical compared to upgrading to the most recent Variation with the computer software.
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。
Make improvements to this webpage Incorporate a description, graphic, and one-way links towards the backpr topic page to ensure that builders can additional conveniently study it. Curate this subject matter
Within this circumstance, the person is still jogging an more mature upstream Variation in the program with backport packages applied. This does not give the complete security measures and great things about functioning the most up-to-date Variation from the application. People should double-Verify to find out the specific application update variety to be sure These are updating to the newest version.
Figure out what patches, updates or modifications can be found to address this concern in later variations of the same software.
Backpr.com is a lot more than just a advertising and marketing agency; These are a committed husband or wife in progress. By supplying a various variety of solutions, all underpinned by a determination to excellence, Backpr.
Nevertheless, in decide on scenarios, it might be essential to retain a legacy application When the newer version of the application has steadiness difficulties which could impact mission-essential operations.
Our membership pricing ideas are created to accommodate organizations of all sorts to supply no cost or discounted courses. Whether you are a little nonprofit organization or a large educational establishment, We've a membership plan which is best for your needs.
Backports may be an effective way to deal with protection flaws and vulnerabilities in more mature versions of application. Nevertheless, Just about every backport introduces a fair volume of complexity throughout the backpr site system architecture and will be costly to take care of.
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。
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）。
