Different results while running a EM clustering process on RapidMiner and weka

lokraj

I am running the EM clustering for the same data using rapidminer and weka for the same parameters. But I found a different result. Here is my process, data, and result. Why this happens does anyone explain? Thanks in advance.

嗨@lokrajso getting different results does not surprise me. k-means clustering uses a local random seed to start the process. I don't see your Weka process so I cannot compare but possibly you're seeing randomness at play.
