File Information
Description

Cluster validation is an important and necessary step in cluster analysis. This visual cluster validation tool CVAP based on GUI provides important tools and convenient analysis environment for validity evaluation of clustering solutions, estimation of the number of clusters and performance comparison between candidate clustering algorithms.

CVAP includes 4 External validity indices, 14 Internal validity indices and 5 clustering algorithms (K-means, PAM, hierarchical clustering and etc.). It supports other clustering algorithms via loading a solution file with class labels, or by adding new codes. And similarity metrics of Euclidean distance and Pearson correlation coefficient are supported.

Some useful information and references are in help files "Readme.txt", please read them first.

 I think your toolbox is just fine. It will be used for me.

i need matlab code hierarchical clustering for image...

Very useful toolbox.
You have done realy a great job on CVAP!

I found this job really good and very usefull. I have include the option of using matrices from the workspace. I thonk that it really improve the usefulness of the GUI.

Very good tool. Does anyone know how to include alternative distances in this GUI?

Very useful, I have looked for such a tool for a long time. Do you have developed a validity indice for subspace clustering ?

Thank you very much, great job !

Hello, this model is very user-friendly with the demo files. However, if I have 8000 parameter sets (each with 3 parameters), how does one prepare the input file? I had a matrix of 8000 rows with 3 columns (no classes) and this didnt seem to work. Any suggestions? THANK YOU!! Cara

I'm looking for method to validate the result cluster with k-means and I exactly refuse to know about validate k-means clustering.do you have any idea?
then i read this article and I want to know how to calculate the error rate of the result for k-means clustering...
is this use SSE(sum square error)?
please replies me...

How to use it. When I type "mainCVAP"
It shows "Undefined function or variable 'mainCVAP'". Why?

I am having trouble uploading a data file. Mine is a .txt, but I still get loads of errors. Why?

??? Attempted to access data(:,1); index out of bounds because size(data)=[0,0].
Error in ==> valid_data_load at 18
   handles.truelabels = data(:,1);

I think this tool is good.

What is the best place to add a validity indices? I saw the place for a new clustering algorithm, but don't see anything similar for indices.

I find there is a problem in the CVAP, when I used the pam.m, it must call the pamc.m, but the pamc.m is not exist in this CVAP
