Performance of DBSCAN

Dear Community,

which alternatives do we have with regard to the performance validation of DBSCAN Clustering in RapidMiner? I saw that centroid based performance operators don't work for DBSCAN as expected. But which alternatives exist in RapidMiner?

Thank you in advance for your answers!

Best regards!

Hi @Muhammed_Fatih_,

Have you tried the Cluster Density Performance operator ?
Look at the process in attached file to understand what I mean...

Hi @lionelderkrikor,

thank you for your answer!

I wanted to try the operator but I've read in the operator description (https://docs.rapidminer.com/latest/studio/operators/validation/performance/segmentation/cluster_density_performance.html) that "This operator is used for performance evaluation of the centroid based clustering methods."This confused me a bit.

Due to the reason that DBSCAN represents a Clustering method of the density-based approach, I don't really know if this performance operator fits or not?

Best regards!
