Clustering with Weka

Hi everyone and happy new year!

I have to analyse a data set with weka clustering, using 3 clustering algorithms and I need to provide a comparison between them about their performance and suitability. The comparison may include a description about how to adjust parameter values of the clustering algorithms to make them perform better. The three algorithms are SimpleKmeans, DBSCAN and HierarchicalClusterer.

So, my questions are: What kind of variables do I need to look at when measuring performance and suitability? The one that I managed to find so far is Within cluster sum of squared errors. And also, which parameter values do I need to adjust in order to make the algorithms perform better?

Thanks!
 
When do you need to have this situation solved? It seems like you have plenty of time to research the appropriate algorithms on the internet. :)
