hi experts,

I got a Arraylist of int[] which contains data like belows:

321,371,361,305,112,88,109,89,115,97,101,91,922,468,586,4333,415047,1
317,370,357,294,113,87,110,89,110,93,107,92,924,468,591,4391,419170,1
306,362,348,265,114,88,110,90,110,91,103,81,908,475,581,4248,416936,2
.......
333,375,352,301,109,88,112,92,110,92,110,96,904,465,574,4374,409852,56
......
317,370,357,294,113,87,110,89,110,93,107,92,924,468,591,4391,419170,88
........
317,370,357,294,113,87,110,89,110,93,107,92,924,468,591,4391,419170,100
........................about 1000 rows and 17 columns !

the last column is used as a class identifier, writing a program for this ,
u may read in the dataset first, divide it into 10 subsets and store to ten 2D array. Use a For-loop to repeat the process 10 times, and do the classification experiment inside
this for loop. the classification experiment is using ED----http://www.nist.gov/dads/HTML/euclidndstnc.html

The ED method is used to measure the similarity between
two feature vectors(rows). For each sample in the testing set, compare it with
all the samples in the training set and find the most similar feature
vector(row) (by using ED, the shortest distance..), then
compare their class ID ( user ID), if match, it counts a correct
classified smaple, it counts a non-match classified sample otherwise.
Then, obtain the correct classification RATE for each fold, and
also the total classification rate.
Finally output the classification rate for each fold to a text file !

thanks !
