I am running the cluster operator. Even after selecting "add cluster attribute", it is not showing in my dataset. What am I doing wrong?

    Hi @dbot, 
    but are you able to view the results before to use the write to excel operator?
    you can introduce a breakpoint after the clustering visualization opertator and review the results?

    Hi @dbot,
    are you working with Cluster Model from Data operator?
    This operator is for converting an external dataset with cluster attribute in a centroid-based cluster that you can use inside of AI Studio (Rapidminer) with other operators that works with Cluster outputs, like Cluster model visualizer. 
    Is you are trying to clustering with AI Studio, there are a lot of operators like K-Means, K-Medoids and so on. 

    Best,

    I am using Kmeans - cluster model operator. I already have the visualizer also included. For some reason, I am unable to see how the clusters were assigned for each row.

    Here is my model. However, even after selecting the labels option, it does not produce the clusters on the dataest used.

    Hi @dbot, 
    Are you connecting the vis output port to the res port?
    Another option is to connect the second clu output port from the clustering operator to the res port and you'll see the dataset with a new attribute for the cluster value.
    can you share your process?

    I tried the alternative option, but it doesn't seem to be working. Maybe because I am  using the multiplier option with clustering? I sent a screenshot of my process. Can you see this by chance?

    @dbot, 
    your process looks fine, but before to export the results, you can check it into the AI Studio. 
    You can right-click on clustering operator and select Breakpoint after. After run your process you are able to see the  clustering  results.
    Also your write excel operator output isn't connected to the res port on the right side
    please check it.

    Yes! That worked. How do I get that to save in my original data source within RapidMiner?
