Deep Node Ranking: an Algorithm for Structural Network Embedding and End-to-End Classification
share
Complex networks are used as an abstraction for systems modeling in physics, biology, sociology, and other areas. We propose an algorithm based on a fast personalized node ranking and recent advancements in deep learning for learning supervised network embeddings as well as to classify network nodes directly. Learning from homogeneous, as well as heterogeneous networks, our algorithm outperforms strong baselines on nine node-classification benchmarks from the domains of molecular biology, finance, social media and language processing---one of the largest node classification collections to date. The results are comparable or better than current state-of-the-art in terms of speed as well as predictive accuracy. Embeddings, obtained by the proposed algorithm, are also a viable option for network visualization.
