node2vec: Scalable Feature Learning for Networks
node2vec : Scalable Feature Learning for NetworksAditya GroverStanford LeskovecStanford tasks over nodes and edges in Networks require carefuleffort in engineering features used by Learning algorithms. Recentresearch in the broader field of representation Learning has led tosignificant progress in automating prediction by Learning the fea-tures themselves. However, present Feature Learning approachesare not expressive enough to capture the diversity of connectivitypatterns observed in we proposenode2vec, an algorithmic framework for learn-ing continuous Feature representations for nodes in Networks . Innode2vec, we learn a mapping of nodes to a low-dimensional spaceof features that maximizes the likelihood of preserving networkneighborhoods of nodes. We define a flexible notion of a node snetwork neighborhood and design a biased random walk procedure,which efficiently explores diverse neighborhoods.
eralizes prior work and can model the full spectrum of equivalences observed in networks. The parameters governing our search strat-egy have an intuitive interpretation and bias the walk towards dif-ferent network exploration strategies. These parameters can also be learned directly using a tiny fraction of labeled data in a semi-supervised ...
