A Gated MLP Architecture for Learning Topological Dependencies in Spatio-Temporal Graphs

no code implementations29 Jan 2024 Yun Young Choi, Minho Lee, Sun Woo Park, Seunghwan Lee, Joohwan Ko

The Cy2Mixer is composed of three blocks based on MLPs: A message-passing block for encapsulating spatial information, a cycle message-passing block for enriching topological information through cyclic subgraphs, and a temporal block for capturing temporal properties.
