What is the random clustering exactly? It performs better than k-means, so I wonder what it does.

Thanks! Joris

    Hi Joris,

    Random Clustering simply iterates over all examples and assigns a random cluster to it. Must be pure chance, if it performs better than k-Means, or your validation process is wrong.

    Best, Marius

    Yes, I was afraid of that :))

    As performance measurement I take the Item Distribution measurement. The other ones don't seem to work with clustering output, or only with one or two. I assument the measurement works ok, so I'm a bit puzzled.

    Can you please post a simple process which depicts your problem? See the link in my signature on how to do that.
