hello, i have a question ,i down load spmf.zip,but i can't find the file "MainTestApriori_saveToMemory.java" in the package ca.pfv.SPMF.tests.there's a file named "MainTestApriori_saveToFile.java",are they the same one? Thank you for your answer!

Hi,

Thanks for letting me know. The file was removed for some reasons. I will update the software to include it.

Here is the content of the file "MainTestApriori_saveToMemory. You can copy it and create the file:

public class MainTestApriori_saveToMemory {

	public static void main(String [] arg) throws IOException{

		String input = fileToPath("contextPasquier99.txt";
		String output = null;
		// Note : we here set the output file path to null
		// because we want that the algorithm save the 
		// result in memory for this example.
		
		double minsup = 0.4; // means a minsup of 2 transaction (we used a relative support)
		
		// Applying the Apriori algorithm
		AlgoApriori apriori = new AlgoApriori();
		Itemsets result = apriori.runAlgorithm(minsup, input, output);
		apriori.printStats();
		result.printItemsets(apriori.getDatabaseSize());
	}
	
	public static String fileToPath(String filename) throws UnsupportedEncodingException{
		URL url = MainTestApriori_saveToMemory.class.getResource(filename);
		 return java.net.URLDecoder.decode(url.getPath(),"UTF-8";
	}
}
