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
理论没讲太明白，直接上算法，甚至还有公式缺失，代码不敢恭维 就像大家说的一样 先看看线性代数、概率论、统计学再来看看这书吧 我这10多年 php、java、c#、js通吃，本想python应该不难，竟然代码部分有东西看不懂了，不得不拿起本python的书对着看...
评分这本书的最大好处是让你能够用最基本的pyton语法，从底层上让你构建代码，实现我们常说的比如邮件过滤，数据分类的应用。很多时候你要写最基本的代码和结构去做这些工作，而不是像kaggle的tutorial或者其他的工程大多数告诉你一个lib库函数去调用，你能看到底层在干什么...

评分理论推导太弱，导致部分代码实现难以理解为什么是这样写，建议配合吴恩达讲义使用。 另外贝叶斯那段代码实现应该是错误的，作者在计算概率的时候把分母给弄错了，还有就是因为python版本问题，在python3上跑书上程序需要对程序进行一些改动。 附代码修改： def classifyNB(vec2...
