Ah ok thanks, I see now. I didn't know the correct term for fuzzy classification but that's what I was trying to describe.

I'm learning the very basics of clustering and classification algorithms. From my understanding, these use hard cutoffs to set boundaries between the groups in the outputs. My question is - do modern algorithms allow for smoothing or "adding weight" to the boundaries, so they are not just hard cutoffs? And if so, are there any applications where you've seen this done?
