Abstract
Most learning algorithms for factor graphs require complete inference over the dataset or an instance before making an update to the parameters. SampleRank is a rank-based learning framework that alleviates this problem by updating the parameters during inference. Most semi-supervised learning algorithms also rely on the complete inference, i.e. calculating expectations or MAP configurations. We extend the SampleRank framework to the semi-supervised learning, avoiding these inference bottlenecks. Different approaches for incorporating unlabeled data and prior knowledge into this framework are explored. We evaluated our method on a standard information extraction dataset. Our approach outperforms the supervised method significantly and matches the result of the competing semi-supervised learning approach.
