DBSCAN performance evaluation
Hi! I'm facing the following problem. I have to compare the performance of K-Means and DBSCAN on a given dataset. I can easily do it with K-Means: But I can't fit the DBSCAN block in place of the K-Means block. The outputs are different and there is no "Cluster Model" to feed the Performance block. The old version of…

How to create Davies Bouldin Index for algoritm DBSCAN ?
Hello... I have a problem, i want to try different algorithms K-Means and DBSCAN on my dataset and compare the result to find Davies Bouldin Index best validation cluster. i can already to make K-means with result DBI but, i can't make modeling design for DBSCAN to find DBI (Davies Bouldin Index). anyone know to create…

New 9.10 DBSCAN
Dear community, I want to ask about the new DBCAN operator which outputted three instances (exa, ori, mod). I wish to perform evaluation using Cluster Density Performance, however neither of those output compatible with the input of the Cluster Density Performance operator. Can someone please give me any good tutorial on…

How to use DB Scan in the latest version 9.10.001
Hi guys, I'm struggling with the operator DBScan in the newest version 9.10.001 that I updated last night. As a result, I can't find the Port "Clu" like the former 9.10.0 to cluster. If you have any suggestions, please let me know. Many thanks. I’m waiting for you. P/s: The first picture is when I did update. Another is…

DBScan clustered back-feeding
Good morning, I am new here and also in rapid miner. I am trying to do a clustering using dbscan. Currently I get the clustering I want by manually giving more or less weight to my features. But I would like to know some operator that automatically does this function. Depending on the input data, the weight that each of…

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!

is there a way to select only records belonging to a particular cluster?
Hi guys, I apologize in advance if the question turns out to be stupid. I have used the DBScan in order to identify the outliers. Now I have two clusters... is it possible to select just the records contained in one of them?

How to perform precision and recall with k-means and DBSCAN algorithms?
Hi all, I want to perform the precision/recall method on a K-means and DBSCAN algorithm. I've added a target label(Workaround) to the sample data set. Because of the map clustering on labels, i'm only able to set k=2. With other numbers it doesn't work because it has to match the amount of labels. Is there another way in…

"Cluster Result"
Hi everyone, I use DBSCAN to cluster my dataset. I know how to label the anomaly cluster (e.g. cluster_2) as false and other as true (by using if statement and set Role). If my dataset changes, the anomaly cluster will change and i can not specify cluster in if statement. how can i determine which cluster has the lowest…

DBSCAN taking very long time
Hello there, I am currently trying to do a cluster analysis with DBSCAN. Since it is my first time to either do a clusteranalysis or using DBSCAN I only have knowledge from papers and online documents. But maybe someone of you is able to help me out: I am analyzing a kind of huge amount of data (I know it's relative). It's…
