Description: 在数据库中发现频繁模式和关联规则是数据挖掘领域的最基本、最重要的问题。大多数早期的研究采用了类似Apriori算法的产生候选级并测试迭代的途径代价是昂贵的，尤其是挖掘富模式和长模式时，Jiawei Han提出了一种新颖的数据结构FP_tree,及基于其上的FP_growth算法，主要用于有效的进行长模式与富模式的挖掘.本文在讨论了FP_growth算法的基础上，提出了用Visual C++实现该算法的方法，并编写了算法的程序。-found in the database model and the frequent association rules is the area of data mining the most fundamental and important issues. Most of the early studies used a similar Apriori algorithm for the selection of candidates and test-iterative way was costly, particularly mining the rich patterns and long model, Jiawei Han proposed a novel data structure FP_tree and on the basis of their FP_growth algorithm used effectively the model for long and rich patterns of excavation. This paper discussed the FP_growth algorithm on the basis of the Visual C of the algorithm, and the preparation procedure of the algorithm. Platform: |

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 Platform: |

Description: FP增长算法的实现与测试(Java实现)
1、程序编译运行环境Eclipse3.20+JDK1.60
2、程序参数说明
-F=filename
-S=support
-C=confidence
filename:数据集文件名，必须位于工程根目录下
support:支持度，位于0-100.0之间的任意数
confidence:置信度，位于0-100.0之间的任意数
例如：-F=anonymous-msweb.data -S=10.0 -C=45.0（参数顺序无关）
3. 程序正确性验证
工程中包含sample.txt文件用来验证。
具体方法：
（1）在AssociationRuleMining 类中，preprocessDataSet函数的最后一条语句替换为fileName = "sample.txt"
（2）在FPgrowth类中，main函数中的 myFPtree.outputARs2() 替换为 myFPtree.outputARs()
（3）输入正确格式的参数，数据集文件名可任意-FP growth algorithm implementation and testing (Java implementation)
1, compiled runtime environment Eclipse3.20+ JDK1.60
2, program parameters that
-F = filename
-S = support
-C = confidence
filename: data set file name, must be located project root directory
support: support, in any number between 0-100.0
confidence: confidence, any number in between 0-100.0
example:-F = anonymous-msweb.data-S = 10.0-C = 45.0 (parameter order has nothing to do)
3. program correctness verification project file contains sample.txt to verify. Specific methods:
(1) AssociationRuleMining class, preprocessDataSet last statement function is replaced fileName = " sample.txt"
(2) in the FPgrowth class, main function in the myFPtree.outputARs2 () replace myFPtree.outputARs ()
(3) Enter the correct format, parameters, file names can be arbitrary data set Platform: |
