Structural Deep Network Embedding - SIGKDD
DeepWalk [21] combined random walk and skip-gram to learn network representations. Although empirically effective, it lacks a clear objective function to articulate how to preserve the network structure. It is prone to preserving only the second-order proximity. However, our method designs an explicit objective function, which
