Hi !
I have applied attached stability process but I am not sure if I correctly selected log parameters for for jaccard and kuncheva indexes. Could you please help me to correct the process and advice how can I interpret the results of kucheva and jaccard index ?

When I import your process, RapidMiner tells me the following:
I need more information, as you are working with an old version of RapidMiner, and you haven't provided information on what plugins are you using, etc.
All the best,
Rodrigo.
