Hey Noel,

ROC curves help you to assess models for a binary target (sensitivity and 1-specificity connect the dots of true positives and false negatives).

Clustering is unsupervised learning, which means you don't need a target.

This is why you don't see ROC curves if you don't have a target that can be assessed in terms of sensitivity and 1-specificity.

I hope it helps,

M
