I am trying to compare the clustering results of KMeans & O-Cluster. I am able to cluster my 4000 records data (ID, V1, V2, V3, V4) using K-means into 50 clusters. I am trying to do the same suing O-Cluster, but it keeps grouping all the data in one cluster. Any idea what I am missing
My table (ID, V1, V2, V3, V4, V5) used to be defined as (Varchar2, float, float, float, float, float). Now, I changed it to (Number, float, float, float, float, float).
Same problem in a different way. Only 700 records out of ~4K were assigned to one cluster!
Thanks Mark, I guess this explains what is happening here as my values look like below, I guess OC is not able to detect any split in the data because of the small difference between the values. Not sure if this makes any sense!
