A Hybrid Membership Latent Distance Model for Unsigned and Signed Integer Weighted Networks

چکیده
Graph representation learning (GRL) has become a prominent tool for furthering the understanding of complex networks providing tools network embedding, link prediction, and node classification. In this paper, we propose Hybrid Membership-Latent Distance Model (HM-LDM) by exploring how Latent (LDM) can be constrained to latent simplex. By controlling edge lengths corners simplex, volume space systematically controlled. Thereby communities are revealed as becomes more constrained, with hard memberships being recovered simplex goes zero. We further explore recent likelihood formulation signed utilizing Skellam distribution account weighted extend HM-LDM (sHM-LDM). Importantly, induced function explicitly attracts nodes positive links deters from having negative interactions. demonstrate utility sHM-LDM on several real networks. find that procedures successfully identify distinct structures, well relate extracted aspects favorable performances in terms prediction when compared baselines. Furthermore, learned soft enable easily interpretable visualizations highlighting patterns.

متن کاملConservative Signed/Unsigned Type Inference for Binaries using Minimum Cut
Recovering variable types or other structural information from binaries is useful for reverse engineering in security, and to facilitate other kinds of analysis on binaries. However such reverse engineering tasks often lack precise problem definitions; some information is lost during compilation, and existing tools can exhibit a variety of errors. As a step in the direction of more principled r...
