Researchers have developed a novel approach for structure learning on clustered data, extending directed acyclic graph (DAG) methods to accommodate variations within different clusters. This new technique estimates a global structure while simultaneously accounting for local cluster-specific effects, drawing inspiration from the fixed- and random-effects framework of classical mixed models. The method introduces a differentiable graph coupling mechanism to ensure acyclicity and employs an efficient first-order optimization method for computation. Experiments demonstrate that this approach can identify dependencies missed by other estimators, proving valuable for analyzing complex, clustered datasets. AI
