技术取得了令人瞩目的成就，在图像识别、自然语言处理、语音识别等领域取得了突破性的进展。这些成就离不开大模型的快速发展。大模型是指参数量庞大的
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。
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。
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。
Backporting is a standard method to deal with a recognised bug throughout the IT setting. Concurrently, counting on a legacy codebase introduces other potentially significant stability implications for corporations. Depending on aged or legacy code could bring about introducing weaknesses or vulnerabilities in your setting.
偏导数是多元函数中对单一变量求导的结果，它在神经网络反向传播中用于量化损失函数随参数变化的敏感度，从而指导参数优化。
CrowdStrike’s details science staff faced this correct Problem. This post explores the crew’s final decision-building system as well as the steps the staff took to update approximately 200K lines of Python into a contemporary framework.
Backporting requires entry to the application’s source code. As a result, the backport might be produced and furnished by the Main progress group for closed-supply software.
Backporting is really a catch-all phrase for almost any action that applies updates or patches from a more moderen Edition of software package to an older version.

Backports may be an effective way to handle protection flaws and vulnerabilities in more mature versions of software package. However, Every backport introduces a good degree of complexity throughout the procedure backpr site architecture and will be highly-priced to take care of.

参数偏导数：在计算了输出层和隐藏层的偏导数之后，我们需要进一步计算损失函数相对于网络参数的偏导数，即权重和偏置的偏导数。
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。
