what follows after clustering
since clustering is unsupervised, there isn't an objective way to evaluate it. Typically, you just observe and see if there is some features for a certain cluster.
I am trying to cluster images based on their similarities with SIFT and Affinity Propagation, I did the clustering but I just don't want to visualize the results. How can I test with a random image from the obtained labels? Or maybe there's more to it?
Other than data visualization, I just don't know what follows after clustering. How do I verify the 'clustering'
