I create a n clusters using SAS miner HP cluster nodes( K means ). but every time I try to replicate the same clusters it give a different clusters. even using EG with different initializations give me different clusters. my questions are : 1- Is there a way to fix this clusters and make it my work replicable? 2- If I can't fixe my clusters is there a way to test the stability of my clusters using for example an overlap rate and said after 75 % we can said that the clusters are stable? 3- I couldn't find any straight forward answer for the stability of the clusters and how it's important. can we speak about the stability of clustering in this situation? is it very important to test the stability before use the clusters? which measures can do that ? is there any nodes in sas miner can do that? I'm a little bit lost with this question of the stability. thank you for your understanding !!
