Mahout主要有协同过滤、聚类和分类三种算法的实现。现在我们就用Mahout来实现经典的Kmeans聚类算法。
首先，下载Hadoop和Mahout。因为Mahout有很多实现是运行在Hadoop上的，所以要先安装Hadoop。
具体怎么安装？简单地说一下：
1. 先安装SSH。
ufw disable 关闭防火墙
cd .ssh/ 进入ssh文件夹，没有的话，下面生产密钥的时候自动生成
ssh-keygen -t rsa 生成ssh密钥
cp id_rsa.pub authorized_keys 复制多一份
ssh localhost 测试是否联通
sudo apt-get install openssh-server 安装ssh服务
net start sshd 启动ssh服务
2. 解压Hadoop
tar -zxvf hadoop-1.1.2.tar.gz 解压tar.gz
3. 添加环境变量
export JAVA_HOME=/usr/local/jdk7 增加环境变量
export PATH=.:$JAVA_HOME/bin:$PATH 增加环境变量
4. 单机运行的话至少修改四个配置文件
5. 其他命令
hadoop namenode -format 格式化hadoop的namenode,datanode不需要格式化
start-all.sh 启动所有的hadoop服务
stop-all.sh 关闭所有的hadoop服务
start-dfs.sh 单独启动hdfs
stop-dfs.sh
start-mapred.sh 启动MapReduce的两个服务
hadoop-daemon.sh start[进程名称] 单独启动进程
jps 查看正在运行的各种进程
ps -e | grep ssh 查看防火墙服务是否开启
ifconfig -a |grep inet 查看网络连接地址
6. Mahout的安装也类似
先解压，再配置环境变量，最后输入mahout命令，有各种算法列出来就是安装成功了！
http://kdd.ics.uci.edu/databases/reuters21578/reuters21578.tar.gz
下载 Reuters21578 文本语料。也可以自己准备数据集。我用我自己的数据集来做实现。
我收集了1000首歌曲的信息，如下：
把这些信息存入mongodb数据库中，以后还要使用，当然不存也可以。然后用java代码取出来，每首歌曲生成一个txt文件。并且做了处理，标签值赋予不同的权重，歌词进行了分词处理。
Map<String,Object> outmap = new HashMap<String, Object>();
outmap.put("flag",false);
List<Song> list = songRepository.findAll();
int size = list.size() ;
String[] strs = new String[size];
if (list != null){
//循环每一首歌曲
for (int i = 0; i < size; i++) {
Song song = list.get(i);
//有权值的标签
StringBuilder sb = new StringBuilder();
for (int j = 0; j < 8; j++) {
sb.append(song.getArtist()).append(" ");
}
for (int j = 0; j < 2; j++) {
sb.append(song.getAlbum()).append(" ");
}
for (int j = 0; j < 5; j++) {
sb.append(song.getType()).append(" ");
}
for (int j = 0; j < 3; j++) {
sb.append(song.getDistrict()).append(" ");
}
for (int j = 0; j < 6; j++) {
sb.append(song.getYears()).append(" ");
}
for (int j = 0; j < 3; j++) {
sb.append(song.getRhythm()).append(" ");
}
for (int j = 0; j < 4; j++) {
sb.append(song.getMood()).append(" ");
}
//无权值的歌词
String strLrc = song.getLrc() ;
//对歌词进行分词
strLrc = SplitWord.splitWordBySpace(strLrc);
sb.append(strLrc);
strs[i] = sb.toString() ;
}
//写出文件
WriteLines.writeStrBecomeTxts("C:\\Users\\xin\\Desktop\\大论文\\Scala","utf-8",strs);
outmap.put("flag",true);
return outmap ;
} else {
return outmap ;
}生成的文件如下：
把这些文件压缩成一个文件，也就是Hadoop可以解析的SequenceFile格式的文件
Mahout seqdirectory -i file:/usr/song-input -o file:/usr/song-output -c UTF-8 -chunk 64 -xm sequential
加file:前缀是指在本地文件系统上寻找，而不是HDFS。-xm sequential 就是本地执行的意思。
-chunk 64 压缩成64M一个文件，HDFS文件系统的单位就是64M。
接着就是把SequenceFile格式的文件转换为向量Vector。把上一步生成的文件放到HDFS文件系统上。运行命令：
hadoop fs -mkdir input hadoop fs -put /usr/song-output/chunk-0 input Mahout seq2sparse -i input -o output -ow --weight tfidf --maxDFPercent 95 --nameVector -a org.apache.lucene.analysis.WhitespaceAnalyzer
-i 输入目录
-o 输出目录
--weight 权重公式
--maxDFPercent 过滤高词频 >95%
-a 指定分词器 因为我们前面已经用IK分过词了，这里直接按空格分词就可以了
各个参数如下图：
生成目录：
root@xin:~# hadoop fs -ls output Warning: $HADOOP_HOME is deprecated. Found 7 items drwxr-xr-x - root supergroup 0 2015-03-30 14:11 /user/root/output/df-count -rw-r--r-- 1 root supergroup 48768 2015-03-30 14:10 /user/root/output/dictionary.file-0 -rw-r--r-- 1 root supergroup 51433 2015-03-30 14:11 /user/root/output/frequency.file-0 drwxr-xr-x - root supergroup 0 2015-03-30 14:11 /user/root/output/tf-vectors drwxr-xr-x - root supergroup 0 2015-03-30 14:12 /user/root/output/tfidf-vectors drwxr-xr-x - root supergroup 0 2015-03-30 14:09 /user/root/output/tokenized-documents drwxr-xr-x - root supergroup 0 2015-03-30 14:10 /user/root/output/wordcount
· dictionary.file-0：词文本 -> 词id(int)的映射。词转化为id，这是常见做法。
· frequency.file：词id -> 文档集词频(cf)。
· wordcount(目录)： 词文本 -> 文档集词频(cf)，这个应该是各种过滤处理之前的信息。
· df-count(目录)： 词id -> 文档频率(df)。
· tf-vectors、tfidf-vectors (均为目录)：词向量，每篇文档一行，格式为{词id:特征值}，其中特征值为tf或tfidf。有用采用了内置类型VectorWritable，需要 用命令”mahout vectordump -i <path>”查看。
· tokenized-documents：分词后的文档。
现在来运行Kmeans算法了！
Mahout kmeans -i output/tfidf-vectors -c output/kmeans-clusters -o output/kmeas -k 10 -x 200 -ow --clustering
参数说明如下：
-i：输入为上面产出的tfidf向量。
-o：每一轮迭代的结果将输出在这里。
-k：几个簇。
-c：这是一个神奇的变量。若不设定k，则用这个目录里面的点，作为聚类中心点。否则，随机选择k个点，作为中心点。
-dm：距离公式，文本类型推荐用cosine距离。
-x ：最大迭代次数。
–clustering：在mapreduce模式运行。
–convergenceDelta：迭代收敛阈值，默认0.5，对于Cosine来说略大。
其中，clusters-k(-final)为每次迭代后，簇的20个中心点的信息。
而clusterdPoints，存储了 簇id -> 文档id 的映射。
生成的结果文件夹kmeans最好拷贝出来看。
hadoop fs -get output/kmeans/* /usr/song-kmeans/ Warning: $HADOOP_HOME is deprecated. hadoop fs -get output/dictionary.file-0 /usr/song-kmeans Warning: $HADOOP_HOME is deprecated. mahout clusterdump -i file:///usr/song-kmeans/clusters-5-final -d file:///usr/song-kmeans/dictionary.file-0 -dt sequencefile -o /usr/song-result/result -n 20 mahout seqdumper -i file:///usr/song-kmeans/clusteredPoints -o /usr/song-result/all
clusteredPoints文件其实就是SequenceFile文件来的。
result文件里面的内容：
可见有太多的无用词汇，分词效果不好，这些词汇需要过滤掉！
其中前面的26是簇的ID，n=7即簇中有这么多个文档。c向量是簇中心点向量，格式为 词文本:权重(点坐标)，r是簇的半径向量，格式为 词文本:半径。
下面的Top Terms是簇中选取出来的特征词。
all文件里面的内容：
Key是ClusterID，上面clusterdump的时候，已经说了。
Value是文档的聚类结果：wt是文档属于簇的概率，对于kmeans总是1.0，/1.txt就是文档标志啦，前面seqdirectionary的-nv起作用了，再后面的就是这个点的各个词id和权重了。
某个簇的数据有点多了，簇与簇之间数据分布不够均匀，可见聚类效果不是很好。还要改善文档质量！
