WebJan 1, 2024 · We propose a novel multi-modality graph neural network (MAGNN) to learn the lead-lag effects for financial time series forecasting, which preserves informative market information as inputs, including historical prices, raw news text and relations in KG. To our best knowledge, this is the first study to explore the lead-lag effects by embedding ... WebMar 2, 2024 · Abstract: Cellular sheaves equip graphs with ``geometrical'' structure by assigning vector spaces and linear maps to nodes and edges. Graph Neural Networks (GNNs) implicitly assume a graph with a trivial underlying sheaf. This choice is reflected in the structure of the graph Laplacian operator, the properties of the associated diffusion …
