Description: fpgrowth算法的java程序
运行程序的命令
java -cp fpgrowth.jar association.fptree.Test 100 sample.txt
其中100 是支持度阈值 sample.txt是样本文件名。
注意：如果样本中的项目过多，可能会产生内存溢出错误
运行程序需要JDK 5.0
欢迎交流：xiangyuan.lippi@yahoo.com.cn-fpgrowth algorithm java procedures procedure for the java-cp fpgro wth.jar association.fptree.Test 100 sample. txt which supports 100 threshold is sample.txt sample file. Note : If the samples of a large number of projects, Memory may have overflow errors operational procedures need JDK 5.0 welcomed the exchange : xiangyuan.lippi @ yahoo.com.cn

Description: 按FPE定阶的
源程序：fpe.cpp
M序列：M序列.txt
白噪声：Gauss.txt
程序中先用依模型阶次递推算法估计模型的参数，再用fpe方法判断模型的阶次。
程序运行结果如下：
n: 1
判断阶次FPE的值: 0.0096406
-0.481665 1.07868
n: 2
判断阶次FPE的值: 0.00875755
-0.446739 0.00498181 1.07791 0.0527289
n: 3
判断阶次FPE的值: 0.0087098
-0.459433 0.120972 -0.0569228 1.07814 0.0390757 0.116982
n: 4
判断阶次FPE的值: 0.000396884
-0.509677 0.4501 -0.200906 0.0656188 1.07991 -0.0156362 0.442989 0.0497236
n: 5
判断阶次FPE的值: 3.2095e-007
-1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771
n: 6
判断阶次FPE的值: 3.23349e-007
-1.14659 0.76933 -0.487651 0.329676 -0.10377 -0.00440907 1.07999 -0.703574 0.447253 -0.235282 0.113587 0.00479688
从以上结果可以看出，当n=5时，fpe值最小，所以这时的模型阶次和参数估计值为最优结果：
3.2095e-007
-1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771-err

Description: 用分段IFS拟合离散序列的matlab程序
看过Hayes的一篇文章 “Using Iterated Function System to Model Discrete sequences”，我用文章中所用的分段IFS模型写了一段matlab程序以拟合一段网络流量（所用的网络流量是用txt文档保存的一维时间序列）。
程序有用分段IFS编码然后再解码合成数据的过程，还包括计算压缩比。 -IFS fitting with discrete sub-sequences of matlab program saw Hayes in an article " Using Iterated Function System to Model Discrete sequences" , I used the articles used in the IFS model of sub-wrote some matlab program to fit a network traffic (used in network traffic is used to save txt document of one-dimensional time-series). Sub-IFS program useful synthesis of the data encoding and then decoding process, and also includes the calculation compression ratio.
