Representation Learning for Multi-View Graphs

Real-world graphs often exist with multiple views, where each view describes a distinct type of interaction among a shared set of vertices. For example, in social networks, interactions between individuals include friendships, professional relationships, and various other types of relationships. Moreover, multiplex graphs are also prevalent in biology, such as protein-protein interactions gathered from various sources. In contrast to traditional single-view graphs, multiple views retain distinct semantics that complement one another. Hence, analyzing these multiple views collectively can offer a more holistic comprehension of the underlying graph, potentially unveiling patterns and relationships that might remain concealed when only examining a single view. In this project, we will investigate the limitations of existing techniques used for learning from multi-view graphs and create an efficient graph neural network framework for modelling these multi-view graphs, with the aim of enhancing downstream tasks such as gene function prediction.
