Preprocessing of Noisy Data. Data Mining and Business Intelligence GTU 2170715

Consider the following values for age attribute of total 9 records:

4,8,15,21,21,24,25,28,34

Implement smoothing by bin medians to smooth these data, using a suitable bin depth.

       Code :

import java.util.*;

public class p5

{

    public static void main(String[] args)

    {

        Scanner s = new Scanner(System.in);

  

        int i;

        System.out.println("Enter Size of Data:");

        int size = s.nextInt();

        int bin[] = new int[size];

       

        System.out.println("Enter Data:");

        for(i=0;i<size;i++)

        {

            bin[i] = s.nextInt();

        }

      

        Arrays.sort(bin);

      

        System.out.println("Sorting is:");

        for(i=0;i<size;i++)

        {

            System.out.println(""+bin[i]);

        }

      

        i=0;

        int k=0,j,temp=0,l=0;

     

        while(i!=((size)/3))

        {

            for(j=0;j<3;j++)

            {

                                         if(j<1)

                                         {

                                                     int a = bin[k+1];

                                                     bin[k+2]=a;

                                                     bin[k] = bin[k+1];

                                         }

                k++;

            }

            i++;

        }

        System.out.println("Final Output: ");

        for(j=0;j<size;j++)

        {

                System.out.println(""+bin[j]);

        }

    }
