链式法则不仅适用于简单的两层神经网络，还可以扩展到具有任意多层结构的深度神经网络。这使得我们能够训练和优化更加复杂的模型。 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。 A backport is most commonly made use of to address safety flaws in legacy software package or older variations with the computer software that are still ... https://sethnfvhu.blogrenanda.com/40299208/top-guidelines-of-back-pr
