Description: A program to find frequent itemsets with the relim algorithm (recursive elimination), which is inspired by the FP-growth algorithm, but does its work without prefix trees or any other complicated data structures. The main strength of this algorithm is not its speed (although it is not slow, but even outperforms apriori and eclat on some data sets!), but the simplicity of its structure. Basically all the work is done in one recursive function of about 60-70 lines of code. The current version can only find free item sets. An extension to closed and maximal item sets is possible and may be available in the future.-A program to find frequent itemsets with th e relim algorithm (recursive elimination). which is inspired by the FP-growth algorithm, but does its work without prefix trees or any oth er complicated data structures.

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.

Description: FP-growth算法的改进C++程序,具有较好的扩展性和应用性,本程序改成用行读取,然后在内存中解析。更有效的方式是采用块读取方式(本人在以前项目中验证过,速度大为提高。)-FP-growth algorithm C++ Procedures, have good scalability and application, the procedure changed to use line to read, and then resolve in memory. More effective approach is the use of block-read mode (I tested before the project, speed greatly improved.)

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
