how to connect between Set Role operator and Apply Model operator
I have two questions. I would appreciate if you would guide me
1-I have a dataset with 5000 samples that do not have labels. On the other hand, I have another dataset with 100 samples labeled and the samples are not in the 5000 dataset. Is it okay to remove the label of 100 samples and cluster with clustering algorithms and after clustering, add the label to 100 samples and see how many algorithms are clustered correctly. And then, if clustering accuracy increased, We cluster 5000 samples with the same algorithm?
2- I run the scenario for my first question in the RapidMiner, but I do not know how to create connection between two operators. Does anyone know how to connect Set Role operator and Apply Model operator together? I will send you the related file and I hope you help me.
َAlso the dataset is available at the below link:
