Gated Graph Neural Networks for Learning Hidden Independent Cascade Dynamics
Anubha Goel, Illia Oleksiienko, Mateusz Wilinski +2
Information and infectious diseases spread through social networks, but the spreading probabilities driving them are hard to estimate without per-node activation times. Application…
Topology-Aware Gaussian Graph Repair for Robust Graph Neural Networks
Anubha Goel, Juho Kanniainen
Graph neural networks have achieved strong performance on graph-structured data, but their effectiveness depends heavily on the quality of the observed graph. In real applications,…
Class of topological portfolios: Are they better than classical portfolios?
Anubha Goel, Amita Sharma, Juho Kanniainen
Topological Data Analysis (TDA), an emerging field in investment sciences, harnesses mathematical methods to extract data features based on shape, offering a promising alternative…
