Unsupervised machine learning.
cheuk yup ip et al refer to K nearest neighbor algorithm as unsupervised in a titled paper "automated learning of model classification" but most sources classify KNN as supervised ML technique. It's obviously supervised since it takes labeled data as input. I also found the possibility to apply both as supervised and unsupervised learning.
