CoLiDE: Concomitant Linear DAG Estimation

2023 · arXiv (Cornell University)

We deal with the combinatorial problem of learning directed acyclic graph (DAG) structure from observational data adhering to a linear structural equation model (SEM). Leveraging advances in differentiable, nonconvex characterizations of acyclicity, recent efforts have …

Filtering as Rewiring for Bias Mitigation on Graphs

2024

Machine learning over graphs (MLoG) has attracted growing attention due to its effectiveness in processing relational data from complex systems such as social networks, financial markets, and the brain. However, MLoG algorithms that use the …
