Information theory and inference, taught together in this exciting textbook, lie at the heart of many important areas of modern technology - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics and cryptography. The book 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. Inference techniques, including message-passing algorithms, Monte Carlo methods and variational approximations, are developed alongside applications to clustering, convolutional codes, independent component analysis, and neural networks. Uniquely, the book covers state-of-the-art 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, the book is ideal for self-learning, and for undergraduate or graduate courses. It also provides an unparalleled entry point for professionals in areas as diverse as computational biology, financial engineering and machine learning.

Probabilities can be used in two ways.
1. Probabilities can describe frequencies of outcomes in random experiments
2. Probabilities can also be used, more generally, to describe degrees of belief in propositions that do not involve random variables
This more general use of probability to quantify beliefs is known as the Bayesian viewpoint. It is also known as the subjective interpretation of probability, since the probabilities depend on assumptions.
Advocates of a Bayesian approach to data modelling and pattern recognition do not view this subjectivity as a defect, since in their view,
you cannot do inference without making assumptions. (查看原文)
The details of the other possible outcomes and their probabilities are irrelevant.
All that matters is the probability of the outcome that actually
happened (here, that the ball drawn was black) given the dierent hypotheses.
We need only to know the likelihood, i.e., how the probability of the data
that happened varies with the hypothesis. This simple rule about inference is
known as the likelihood principle.
The likelihood principle: given a generative model for data d given
parameters [;\theta;], [;P(d|\theta);], and having observed a particular outcome
[;d_1;], all inferences and predictions should depend only on the function
[;P(d_1|\theta);].
In spite of the simplicity of this principle, many classical statistical methods
violate it. (查看原文)

图文并茂,但是有点废话太多,数学不严谨。

(读过部分章节)与很多教材不同的是,把很多东西放在一起讨论,很有意思。 适合做个补充类读物。要是学信息论或者机器学习还是以其他教材为主吧

信息论课程教材,上课时扫过一遍,后来做研究又细读了和LDPC码相关的内容。绝对是能让人获取观察世界新视角的神书,全面展示信息论的威力,开启系统设计的大门。唯一的缺陷是无法从中看到系统科学近20年的发展。但种子已经种下,未来会反复阅读。
