New SURE-Ridge method advances causal discovery in linear Gaussian DAGs

Researchers have developed SURE-Ridge, a novel non-iterative estimator for causal discovery in linear Gaussian structural equation models with equal variances. This method uses adaptive regularization parameters selected by Stein's unbiased risk estimate (SURE) and an adaptive thresholding procedure to extract a Directed Acyclic Graph (DAG). SURE-Ridge demonstrates superior performance in small-sample regimes by achieving the lowest structural Hamming distance and offers the fastest run times compared to existing methods like NOTEARS, DAGMA, and GBNSL.
