The authors propose a skyline-based approach for member promotion in social networks and systematically study the problem in two different settings: unequal-weighted social networks and equal-weighted social networks. The paper, by Hu et al., "A Unified Framework for Semi-Supervised PU Learning," proposes a new framework that integrates a range of existing semi-supervised PU learning algorithms to better tackle the problem of learning from positive yet unlabeled data. The authors also develop an automatic KL-divergence learning method capable of utilizing the knowledge of unlabeled data distributions. The experimental results demonstrate the better performance of their approach.
