Java implementation of the Apriori algorithm for mining frequent itemsets - using multiple threads (default 8)
View Apriori.java
import java.io.*;
import java.util.*;
/** The class encapsulates an implementation of the Apriori algorithm to compute frequent itemsets.
*
* This version uses multiple threads to go through the dataset and is therefore 3x faster than the 1 thread version.
*
* Notice: To enable progress tracking (CLIProgressBar) follow these steps:
* 1. download this class and put it on the classpath: https://gist.github.com/lovromazgon/9c801554ceb56157de30
