It's been said that data is the new "dirt"—the raw material from which and on which you build the structures of the modern world. And like dirt, data can seem like a limitless, undifferentiated mass. The ability to take raw data, access it, filter it, process it, visualize it, understand it, and communicate it to others is possibly the most essential business problem for the coming decades.

"Machine learning," the process of automating tasks once considered the domain of highly-trained analysts and mathematicians, is the key to efficiently extracting useful information from this sea of raw data. By implementing the core algorithms of statistical data processing, data analysis, and data visualization as reusable computer code, you can scale your capacity for data analysis well beyond the capabilities of individual knowledge workers.

Machine Learning in Action is a unique book that blends the foundational theories of machine learning with the practical realities of building tools for everyday data analysis. In it, you'll use the flexible Python programming language to build programs that implement algorithms for data classification, forecasting, recommendations, and higher-level features like summarization and simplification.

As you work through the numerous examples, you'll explore key topics like classification, numeric prediction, and clustering. Along the way, you'll be introduced to important established algorithms, such as Apriori, through which you identify association patterns in large datasets and Adaboost, a meta-algorithm that can increase the efficiency of many machine learning tasks.

读后感

如果你是机器学习的入门者，如果你想快速看到算法的执行效果，那么这本书适合你。 作者把算法的基本原理讲的很清楚，而且代码是完整可执行的。当然，如果你想了解算法背后的数学原理，还需要花时间去复习一下概率论、高等数学和线性代数。 BTW：读者最好有编程经验，有抽象思维。  

人工智能的脉络 机器学习是人工智能的一个分支。 人工智能的研究历史有着一条从以“推理”为重点，到以“知识”为重点，再到以“学习”为重点的自然、清晰的脉络。 机器学习是实现人工智能的一个途径，即以机器学习为手段解决人工智能中的问题。 从学习方式来讲，机器学习包括...  

特别适合新手，特别适合新手，特别适合新手。长度适中，举例形象，概念浅显通俗。难得有一个条理清楚 逻辑不迷糊 不堆砌代码打哈哈的书。基于这个理由bonus给五星，以后给别人推荐就这本了。 尤其是前面几章，介绍机器学习的基本概念。作者给我们指明了一个做ML的基本要求：“...  

用户评价

看这书可以同时入门机器学习，python，mapreduce，作者可以几个方面都讲清楚，真不容易

超级赞的入门好书，很多之前模糊的概念都通过本书中的例子弄明白了

内容比较基础，有py代码，对着看比较容易理解。

书中介绍了“十大机器学习算法”中的八种，虽然不深入但是讲解清楚容易理解和上手，是本佳作。从覆盖面上来看没涉及到随机森林算法和神经网络是一个小遗憾。

读它是为了熟悉Python语言；内容是在不敢恭维。
