资源描述一、环境环境：Ubuntu14、Hadoop2.6，Eclipse、NLPIR/ICTCLAS2015等； 二、算法简介： 1、此项目是基于Hadoop2.6进行MapReduce并行开发； 2、此项目是文本分类的文本预处理和文本表示部分，包括分词，去停用词，特征选择和文本表示等（分类算法采用的是随机森林算法，暂时未开放，读者可自行采用Mahout或Weka进行验证）； 3、分词采用的是NLPIR/ICTCLAS2015；文本表示采用的是VSM模型，权重计算采用TFIDF进行文本表示；特征选择采用CHI算法（卡方统计）； 4、关于并行分词环境搭建，可参考我的博客http://www.cnblogs.com/merru/p/4917665.html 5、关于Hadoop环境搭建，可参考我的博客http://www.cnblogs.com/merru/p/4901528.html和http://www.cnblogs.com/merru/p/4905118.html。

Parallel Computing for some samples!

特征有限元关于AC方程程序加快速稳定双共轭梯度算法(characteristics finite element)

提出了一种以目标函数变化量作为评价函数的改进禁忌搜索算法,并进行了理论分析,然后将其与有效禁忌搜索算法作了性能比较。通过比较三个公共测试数据集的计算结果,验证了本文提出的禁忌搜索算法的可行性和有效性。(Proposed a change in the objective function as the evaluation function of the improved tabu search algorithm, and has carried on the theoretical analysis, then made a performance comparison with tabu search algorithm is effective. By comparing the calculation results of three test data set, and verified the feasibility and effectiveness of the proposed tabu search algorithm.)

This book is for students and researchers who are interested in scientific computation. The book has a dual purpose: first, it is a textbook for a course on parallel scientific computation. Second, the book is a source of example parallel algorithms and programs for computational physicists and chemists, and for other computational scientists who are eager to get a quick start in parallel computing and want to learn a structured approach to writing parallel programs.
