Hi everyone,

How can we use clustering in developing a predicitve model. I have implemented a dataset using k-means algorithm. i gave number of clusters as '2'. I got cluster1 and cluster2 . But i am getting the "sum of squared errors :1037.0" is there any effect of this in the output. is my clustering is wrong or its having a poor performance?

Cluster 1 is red colour and cluster2 is blue colour in the "visualize errors clusters". In that i am getting in some group as a combination of cluster1 and 2. so whats the interpretation from it.

how will you interpret the clusterring algorithm with respect to aim of developing the predictive model ?

please help- me out. its getting interested to work in WEKA........

Please i want some quick replies.... HELP!!

Thanking you
