How can I validate a DBSCAN clustering using only internal criteria?
Hello, I'm trying to do a validation of different clustering models using ONLY internal criteria. With centroid-based clustering, like K-means and K-medoid, I used DB index and an extension that evaluates the silhouette index. My problem is that DB and silhouette indexs are not available for DBSCAN, and the others operators of RapidMiner Studio like density, or item distrubution make no sense to me in this case.
I saw this post, but I couldn't find an answer: https://community.rapidminer.com/t5/RapidMiner-Studio-Forum/Cluster-Performance-DBScan-and-agglomerative-Clustering/m-p/40748#M27683
By the way, I readed that in previous versions of RapidMiner existed an operator called "Cluster internal validation". https://community.rapidminer.com/t5/RapidMiner-Studio-Forum/Cannot-find-the-cluster-internal-validation-operator-in-rapid/m-p/25745
Is this operator still available?
