K-means clustering

Hey there,
I want a working algo of k-means algorithm.

Facing problems with biclustering..!!

Hoping for a +ve reply this time.. :p
 

If you are familiar with MATLAB, there is a k-mean function in matlab. If you plan to use C/C++, you can look at the book called numerical recipe in C to get k-mean c-function.

k-means in general is fairly simple to implement.
The results of the algorithm depend a lot on your parameters.
First off, finding true k is essential.
Use a cross validation with a scree plot to find the true k.

k-means tends to be sensitive to the random clusters generated at the start of the algorithm.
So run it several times to find the best result.

Also consider Fuzzy k-means or even EM algorithm (depends on how much noise you have and the origin of the data).

Also take a look at: Cluster Analysis
If you don't have access to MATLAB, try Weka (it's free) Weka 3 - Data Mining with Open Source Machine Learning Software in Java
