cryptexcode / AprioriAssociationMining

A fast implementation of Apriori Association Mining algorithm. It uses Java Bitset data structure to make operations faster and uses several pruning techniques to improve the performance. It usually take a few seconds to mine the associations.

How to Run

It takes 4 parameters. a) minimum support b) k c) transaction file path d) output file path

1. Run from jar: cd to the source directory. Command structure is following.

java -jar dist/Apiori_DM.jar <minimum_support> <input_file_path> <output_file_path>

* Example command:

* ```
java -jar dist/Apiori_DM.jar 4 3 /WorkSpace/Courseworks/COSC_6335_DM/Project1/proj_1/transactionDB.txt /WorkSpace/Courseworks/COSC_6335_DM/Project1/my_outputs/sup_4_k_3.txt

2. Run from source code:

• The code is in MineItemsets class.
• The constructor takes the 4 input parameters same as jar.
• Call this constructor from somewhere like following.

public static void main(String[] args) {
        int min_sup = 3;
        int k = 4;
        String inputFilePath = "";
        String outputFilePath = "";
        
        new MineItemsets(min_sup, k, inputFilePath, outputFilePath);
}
