I will review the work on graph-based approaches to semi-supervised learning done in collaboration with Xiaojin Zhu and John Lafferty, placing it in the context of some of the related work in the literature. I will then step back and try to bring up the issue of whether we have a coherent probabilistic framework for semi-supervised learning, and whether a Bayesian approach can and should be taken to this problem.
