Hi :
Have you seen the open source K-Means C# Implementation on this site?

It is functional, not completely tested but it looks like it will meet your needs.

Could you describe the K-Means algorithm and techniques you implemented?

Also on this site, their is a link to a free source code Visual basic 6 kmeans algorithm implemenation.

Also, have you thought of getting your hand on a SQL Server 2005 Beta Version and using the Clustering Algorithm?

Please let me have your comments and thoughts along these or any other lines.

Thanks

Hi There

Thanks for your reply. I have seen your C# project on this site and have already downloaded it and played with it. I have managed to import the project into Delphi 2005 and convert it to a Borland C# Project.

My Problem is that I am unsure how to use the classes in your library and was wondering if you had a real world example application that implements your library and uses it to cluster a sample array of data or datatable.

I have been trying unsuccessfully for about a week to write the algorithm in Delphi. I can get the initial clusters ok, but I need to optimize the code and figure out how to calculate SSB, SSW and Calinski index correctly. This is my first attempt at clustering and I have written my code based entirely on clustering documentation that I have found online.

The Eculidian distance function is what I use in my code.

I would like to use your code and my code to cluster my data and compare results whilst debugging. That way I can see where I am going wrong.

My Data is an array with the following structure:
Store Number, Sales Units, Sales Value, Store Bays

I have up to 1000 rows of data in my array. I basically need to cluster stores for similarity purposes before I can use the forecasting engine I developed a few months ago. Problem is that some stores lack sales history (newly opened stores) and I need 24 months of history to forecast accurately, hence the need to cluster by similarity and use similar stores for forecastable values.

Thanks again for your reply and I look forward to hearing from you again.

Kind Regards

Kingsley, you can count me in!  I know little about data mining, but I would like to contribute code for distributing search indexes across multiple machines, where many machines could fail.

Is this an example of datamining?  I hope so, because if it is, then I found my topic

iam very interested to join you group in developing a project

i will participate in algorithms like native baye sclassification and others

hi skuty,

can you send me the source code for the rough set theory. I am currently doing some research on that algorithm, but i have lack of resources about the rough set. i really need your help. please mail me lizaliez@yahoo.com. TQ

sir i want to perform data mining in VB.NET. Actually i want to sofware a Data Mining Toolkit

Hi

I need an implementation of fuzzy association rule, but I can’t found any algorithms,

I’ll be very thankful if you help me to know how that algorithm is exactly.

Thanks a lot.

Can i have a new version of Neural Network Backpropagation ??? where can i get it???Cause i want to compare the source with mine

You can get the VB.NET and C# versions here

Hi,

I need to source code of Apriori Algorithm with C program. Could you help me?

Thanks.

it would be gr8 to join u

Hi, I'm Nicola, an Italian university student...I'm doing a project for the university and I need the source codes for the nearest neighbour, farthest neighbour, UPGMA in C#...(if you haven't this code in c#, you can send me these in C)may you help me?!

thank a lot<1

Heloo I am doing a project in data mining. It will be useful for me if you post the c# code for Apriori Algorithm.

Please it is very urgent..........
