Information theory and inference, often taught separately, are here united in one entertaining textbook. These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

读后感
学习信息论的时候，老师推荐的，然后就买来了。实例很多，习题也很经典，花费了一个学期看了一遍，感觉对信息论的理解完全高了好多个层次。

评分信息论是我觉得最有用的课程之一，不管是科研，还是现实生活。 首先从信息论的角度看数字编码，从二进制，十进制，再到二十进制，其实是在用越来越多的符号来编码无穷尽的数字。二进制只需要两个符号0，1就可以编码所有数字，每个字符信息量较小，代价就是编码长度及其长，不利...
