java source code for k means clustering

[thijo]

hi,
I am very naive to java. my project is in data mining where i have to implement k means clustering.
the task is like this
1.reads a csv file and stores the attributes in a matrix format
2.clusters the matrix data depending on the euclidean distance measure.
3. the centroid value the user must give
4. the mean should be recalculated for the clusters to maintain accuracy
4. the output should be the clusters or groups
thanks in advance

I don't know why you're telling us what you need to do, but I wish you luck.

hi,
I am very naive to java. my project is in data mining where i have to implement k means clustering.
the task is like this
1.reads a csv file and stores the attributes in a matrix format(6000rows and 86 columns). From that i have to choose certain columns(attributes) for clustering
2.clusters the matrix data depending on the euclidean distance measure.(minimum distance) from the user given centroids
3. the centroid value the user must give.
4. the mean should be recalculated for the clusters to maintain accuracy
4. the output should be the clusters or groups
please help to code in java. do i have any packages in java to implement this
thanks in advance

I am very naive to java.

So buy / borrow / steal a book on Java read it (there is also the " Starting Java " sticky which should interest you) and get up to speed on it. I think your class instructor / firm would have given you this assignment only after they were **sure** that you could handle it. However if you gave them a false impression of your skills then I do not know .....

do i have any packages in java to implement this

Weka is a data mining tool written in Java, so you might want to check out how it works. I however have never used, so do not have a clue about it.

please help to code in java

Help yes, but do not expect us to do the entire work for you. First you show us what you have tried. Reading data from a CSV file is simple enough show what you have achieved there ??

Put your code inside code tags, like this:-

[code=java]
// Your code here.
[/code]

The rest like the output you are getting, post it as :-

[code]
//Output on compiling / running the program.
[/code]

1) You're posting to a thread that is two months old, start you own thread.
2) You have not explained your problem nor have you shown what you've done to reach the point where you got an error. (if all you did was copy and paste someone else's code you're not going to get help.)

i am in need of k means clustering for the face recognition which is for my research.so i need a sample code in any language(c,c++,java or vb)
