I am a new user of weka. I met a problem when I used cluster. I used the cluster to mining the iris.arff, the result is 45 clusters with is totalling different with the 3 clusters in the presentation.ppt in the same parameters.

Incorrectly clustered instances : 94.0  62.6667 %

I don't know why!

thanks a lot!
