Fractionally-Supervised Classification [PDF]

open access: yesJournal of Classification, 2015
Traditionally, there are three species of classification: unsupervised, supervised, and semi-supervised. Supervised and semi-supervised classification differ by whether or not weight is given to unlabelled observations in the classification procedure. In unsupervised classification, or clustering, all observations are unlabeled and hence full weight is

Self-Supervised Node Classification with Strategy and Actively Selected Labeled Set

open access: yesEntropy, 2022
To alleviate the impact of insufficient labels in less-labeled classification problems, self-supervised learning improves the performance of graph neural networks (GNNs) by focusing on the information of unlabeled nodes.
