In the Elbow graph with the data of SSE of the k-means, I obtain the value in the graph and they don't decrease.
In your opinion, what are the possible problems?

    Hi @ElenaVet,

    A priori, the curve of SSE according to k (the number of cluster(s)) is increasing because 
    RapidMiner works with negative values (RapidMiner searches to maximize the value of SSE in you are using an Optimization Loop).

    See this thread for the details : 
    https://community.rapidminer.com/discussion/comment/61654#Comment_61654

    Hope this helps,

    If you don't obtain an increasing curve or more generally you obtain an "exotic" curve, please share your data and process in order
    we can reproduce and understand what's going on...

    Regards,

    Lionel
