说明：  这本书最初是我学习 Neural Networks and Deep Learning 时做的中?笔记，因为原书中有很 A A 多数学公式，所以我? LT E X 来编写和排版，并将所有 LT E X 源码放置在 GitHub。其中部分内容 取? Xiaohu Zhu 已经完成的翻译来避免重复的?作。
(This book was originally Neural Networks and Deep Learning I learned to do in notes, because there is a A A mathematical formula of the original book, so I LT E X to write and typesetting, and all LT E X source is placed in the GitHub. Take part Xiaohu Zhu has completed the translation to avoid repeated for.)
