如何给神经网络图添加偏差和权重？

Question

边注：

请始终添加最小工作示例平均能量损失。
如果您添加结果图片，以便人们可以直接看到您期望实现的目标，那就太好了。其他问题或答案的图片没有帮助。链接就足够了。
请记住阐明您的具体问题或添加其他详细信息以准确突出您的需求。请参阅如何询问帮助澄清问题的页面。

更新答案参考您的评论+改进的问题：

这仅仅是一个短暂的起点！

只是为了帮助您调整代码。起点可以是以下内容。我希望它能帮助您看到理解代码的真正问题。我添加了一个新行（称为\y=0）并在列\N=2（隐藏层 2）中添加了一个新节点（\node[bias]）。一般来说，该选项minimum size=<..>可能对所有节点样式都有用，请参阅bias/.style={...。标题用移动yshift=2cm。从偏差到输出的虚线箭头：\path[dashed] (H2-0) edge (O);。所有更改都用标记%<-- added %%%%%%。
