Hi dear friends
How can I use Normalized Mutual Information (NMI) for Clustering? like K-Means or DBSCAN
I attach the file
Thank's
You could build a process using the k-means and/or DBSCAN operators?
I used K_Means and DBSCAN, but I want to evaluate these methods by NMI.
You might want to check out the Mutual Information Matrix operator. See below.
