  title = {Learning from Labeled and Unlabeled Data Using Random Walks},
  abstract = {We consider the general problem of learning from labeled and
  unlabeled data. Given a set of points, some of them are labeled,
  and the remaining points are unlabeled. The goal is to predict the
  labels of the unlabeled points.  Any supervised learning algorithm
  can be applied to this problem, for instance, Support Vector
  Machines (SVMs). The problem of our interest is if we can
  implement a classifier which uses the unlabeled data information
  in some way and has higher accuracy than the classifiers which use
  the labeled data only.  Recently we proposed a simple algorithm,
  which can substantially benefit from large amounts of unlabeled
  data and demonstrates clear superiority to supervised learning
  methods. In this paper we further investigate the algorithm using
  random walks and spectral graph theory, which shed light on the
  key steps in this algorithm.},
