HI,
I am a final year student of master's of engineering in computer science & currently doing thesis work in Association rule data mining. I am stuck in a small problem regarding rapid miner. I want to apply FP- growth algorithm on 2 simple java programs using rapid miner to find Association rules, but i am not able to do so.
I want to apply FP growth algorithm on 2 java programs and find the association rules from them.
What i have done till now:-
1. Saved the two programs in .txt files (Copied programs to notepad and saved it as program1.txt and program2.txt)
2. Selected the Process document from Files operator in rapid miner.
3. Then applied Tokenize operator, Filter token , Stem(snowball) and Transform cases operator [for processing the text].
4. After processing the text , I used Numerical to Binomial conversion operator.
5. After it, I aplied FP growth operator and lastly Create association rules operator.
6. Linked everything correctly.
All these steps were followed but "No rules found" comes up everytime.
I tried the same procedure on a group of six simple C programs and it worked well. Rules were also framed well
. I don't understand why it is not working for two Java programs. If anybody there can help and guide me, i would be more than grateful.
The 2 java programs I am taking as input are stated below:
Program 1 :-
package codeclone;
import java.util.Scanner;
public class Example1 {
public static void main(String[] args) {
int input;
System.out.println("The super insano calculator");
System.out.println("enter the corresponding number:");
Scanner reader3 = new Scanner(System.in);
System.out.println("1. Add | 2. Subtract | 3. Divide | 4.Multiply");
input=reader3.nextInt();
int a , b;
Scanner reader = new Scanner(System.in);
System.out.println("Enter the first number");
//get user input for a
a=reader.nextInt();
Scanner reader1 = new Scanner(System.in);
System.out.println("Enter the second number");
//get user input for a
b=reader1.nextInt();
switch (input){
case 1: System.out.println(a + " plus " + b + " equals " + add(a, b)); break;
case 2: System.out.println(a + " minus " + b + " equals " + subtract(a, b)); break;
case 3: System.out.println(a + " divided by " + b + " equals " + divide(a, b)); break;
case 4: System.out.println(a + " times " + b + " equals " + multiply(a, b)); break;
default: System.out.println("your input is invalid!"); break;
}
}
public static int add(int first, int second) {
return first + second;
}
public static int subtract(int first, int second) {
return first - second;
}
public static int divide(int first, int second) {
return first / second;
}
public static int multiply(int first, int second) {
return first * second;
}
}
Program 2 :-
package codeclone;
import java.util.Scanner;
public class Example2 {
public static void main(String[] args) {
int input;
System.out.println("The super insano calculator");
System.out.println("enter the corresponding number:");
Scanner reader3 = new Scanner(System.in);
System.out.println("1. Add | 2. Subtract | 3. Divide | 4.Multiply");
input=reader3.nextInt();
int c , d;
Scanner reader = new Scanner(System.in);
System.out.println("Enter the first number");
//get user input for c
c=reader.nextInt();
Scanner reader1 = new Scanner(System.in);
System.out.println("Enter the second number");
//get user input for d
d=reader1.nextInt();
switch (input){
case 1: System.out.println(c + " plus " + d + " equals " + ad(c, d)); break;
case 2: System.out.println(c + " minus " + d + " equals " + sub(c, d)); break;
case 3: System.out.println(c + " divided by " + d + " equals " + div(c, d)); break;
case 4: System.out.println(c + " times " + d + " equals " + mul(c, d)); break;
default: System.out.println("your input is invalid!"); break;
}
}
public static int ad(int fir, int sec) {
return fir + sec;
}
public static int sub(int fir, int sec) {
return fir - sec;
}
public static int div(int fir, int sec) {
return fir / sec;
}
public static int mul(int fir, int sec) {
return fir * sec;
}
}
Can anybody please tell me what's wrong and why i am not able to find association rules.
Thank you for your consideration. Hope I get the response soon. It is urgent. A video or if not then a little bit of guidance will also help. I shall be more than grateful.

Hi there,
Association rules are a special interest of mine, so here's my two cents...
If someone asked you to make rules from examining just two shopping baskets what would you say? Your two programs are two shopping baskets full of words, you need more! Just consider what conditions would need to be true for frequent item sets to get made, and no frequent itemsets means no rules, whatever the frequency threshold.
Nice use of the technique, as mentioned it's a speciality of mine, check out my website, that does it on news.
Best

Following is the XML file of the work done by me in rapid miner. The two java programs stated in the first post were taken as input for forming association rules. Please check why no rules are being made recommend editions. I am totally new to rapid miner.
