当前，深度学习和人工智能的发展和应用给人们留下了深刻的印象。神经网络是深度学习和人工智能的关键元素，然而，真正了解神经网络工作机制的人少之又少。本书用轻松的笔触，一步一步揭示了神经网络的数学思想，并介绍如何使用Python编程语言开发神经网络。

本书将带领您进行一场妙趣横生却又有条不紊的旅行——从一个非常简单的想法开始，逐步理解神经网络的工作机制。您无需任何超出中学范围的数学知识，并且本书还给出易于理解的微积分简介。本书的目标是让尽可能多的普通读者理解神经网络。读者将学习使用Python开发自己的神经网络，训练它识别手写数字，甚至可以与专业的神经网络相媲美。

本书适合想要了解深度学习、人工智能和神经网络的读者阅读，尤其适合想要通过Python编程进行神经网络开发的读者参考。

这是一本精心编写、给完全初学者的图书。它带领读者构建一个真正、有效的神经网络，而不需要读者具备任何复杂的数学知识和深度学习的理论。

——M Ludvig

强烈推荐本书。这本书使得人工神经网络的概念非常清晰而容易理解。读者应该尝试重复本书中给出的示例，以便让本书发挥大的作用。我就是这么做的，效果不错！

——美亚的一位读者

如果你对人工智能或神经网络感兴趣的话，这应该是你的第1本入门书。本书对主题的介绍非常清晰，几乎涉及理解神经网络所需的所有知识，包括微积分、统计、矩阵、编程等等。

——Niyazi Kemer

这是一本优秀的入门图书，它有几个显著特点。它细致而透彻地介绍了神经网络。它用非常精简、实用的方式介绍了数学知识，特别是矩阵乘法和一些简单的微积分，使得读者能够很容易接受一次数学训练。它使用IPython作为计算平台，引导读者使用Python编写神经网络。

——Daniel Oderbolz

Content Description

本书首先从简单的思路着手，详细介绍了理解神经网络如何工作所必须的基础知识。第一部分介绍基本的思路，包括神经网络底层的数学知识，第2部分是实践，介绍了学习Python编程的流行和轻松的方法，从而逐渐使用该语言构建神经网络，以能够识别人类手写的字母，特别是让其像专家所开发的网络那样地工作。第3部分是扩展，介绍如何将神经网络的性能提升到工业应用的层级，甚至让其在Raspberry Pi上工作。

Author Description

塔里克·拉希德拥有物理学学士学位、机器学习和数据挖掘硕士学位。他常年活跃于伦敦的技术领域，领导并组织伦敦Python聚会小组（近3000名成员）。
