Data Mining
What is Data Mining?
-
Automatically searching large data to find patterns and trends that go beyond simple analysis.
-
Using sophisticated mathematical algorithms, artificial intelligence, statistical. analysis, and database systems to find patterns.
-
Predicts likely outcomes.
***Algorithms are the core of Data Mining***

The APRIORI ALGORITHM keeps track of the frequency of item in a database. These frequent items are then used to determine patterns in the large data. These databases contain transactions data. The apriori uses breadth-first search and Hash tree structures to count the frequency data items.

How to Run the Apriori Algorithm in Java Using Blue J
STEP 1
-
Download Blue J which is a free Java Development Environment designed for. beginners, used by millions worldwide.
-
Dowload Link http://www.bluej.org/
-
Make sure to get the correct version for your OS that includes JDK
-
Next run the executable and install Blue J.
.
STEP 2
-
Once You have Blue J installed open Blue J and under Project select new Project and name it Apriori Algorithm.
-
Add a new class and name it Apriori.
STEP 3
-
Next open up the apriori class folder and select all the text and cut it.
STEP 4
-
Next we will get the source code from this link:
-
Copy and paste the Apriori.java code from the above link into your empty apriori class.
-
Make sure you copy all the code from line 1 to line 315.
STEP 5
-
Next download the chess.dat file and save it into your apriori algorithm folder that was created when we created the new project in BlueJ.
-
Next compile your code and run the program by right-clicking on your apriori class and clicking on the method void main(String[] args) and then click ok on the method call window pop up.
-
Your algorithm should get to work and compute hundreds of computations in a matter of seconds.
-
Scroll down to the writing in RED and it will give you information about your chess.dat file which contain rows with numbers. Each row represents a transaction
