KNH: Multi-View Modeling with K-Nearest Hyperplanes Graph for Misinformation Detection

no code implementations15 Feb 2021 Sara Abdali, Neil Shah, Evangelos E. Papalexakis

In this work, we introduce a novel generalization of graphs i. e., K-Nearest Hyperplanes graph (KNH) where the nodes are defined by higher order Euclidean subspaces for multi-view modeling of the nodes.
