网络的权重和偏置如下（这些值是随机初始化的，实际情况中会使用随机初始化）： This method can be as clear-cut as updating numerous traces of code; it may contain A significant overhaul that may be distribute throughout several documents with the code. 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... https://backpr29371.nizarblog.com/34159124/the-definitive-guide-to-backpr
