翻译 划分聚类分析: K均值和基于中心点的划分(PAM)
一.原理K均值聚类最常见的划分方法是K均值聚类分析。从概念上讲, K均值算法如下: (1) 选择K个中心点(随机选择K行); (2) 把每个数据点分配到离它最近的中心点; (3) 重新计算每类中的点到该类中心点距离的平均值(也就说,得到长度为p的均值向量,这里的p是变量的个数); (4) 分配每个数据到它最近的中心点;...

Bayesian Reasoning and Machine Learning
Machine learning methods extract value from vast data sets quickly and with modest resources. They are established tools in a wide range of industrial applications, including search engines, DNA sequencing, stock market analysis, and robot locomotion, and their use is spreading rapidly. People who know the methods have their choice of rewarding jobs. This hands-on text opens these opportunities to computer science students with modest mathematical backgrounds. It is designed for final-year undergraduates and master's students with limited background in linear algebra and calculus. Comprehensive and coherent, it develops everything from basic reasoning to advanced techniques within the framework of graphical models. Students learn more than a menu of techniques, they develop analytical and problem-solving skills that equip them for the real world. Numerous examples and exercises, both computer based and theoretical, are included in every chapter. Resources for students and instructors, including a MATLAB toolbox, are available online.
