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
算法从输出层开始，根据损失函数计算输出层的误差，然后将误差信息反向传播到隐藏层，逐层计算每个神经元的误差梯度。
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 situations, the consumer maintains the older Variation of the program since the newer Edition has security troubles or may very well be incompatible with downstream applications.

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。

一章中的网络缺乏学习能力。它们只能以随机设置的权重值运行。所以我们不能用它们解决任何分类问题。然而，在简单
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。
