The semi-supervised learning problem is to assign labels to a dataset given a small number of training labels. We consider random geometric graphs and a Lp finite difference regulariser. In the talk I will discuss the asymptotic behaviour when the number of unlabelled data points increases whilst the number of training labels remains fixed. We show a delicate interplay between the regularizing nature of the functionals considered and the nonlocality inherent to the graph constructions.
