lovromazgon / Apriori.java
Last active Dec 10, 2015 — forked from monperrus/Apriori.java
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
* 2. uncomment lines 229 and 243

import java.io.PrintStream;
/**
* The CLIProgressBar outputs a progress bar and the time remaining for completing a task.
* <p>
* To use it you must provide the total size / total number of iterations for your task (e.g. file length)
* and update the current position after each iteration.
