New framework tackles causal discovery with unobserved confounders

Researchers have developed a new framework for causal discovery in linear models, specifically addressing challenges posed by unobserved confounders. This approach utilizes the Widely Applicable Bayesian Information Criterion (WBIC) and approximates it using Automatic Differentiation Variational Inference (ADVI). The method incorporates a differentiable search over acyclic directed mixed graphs (ADMGs) through Gumbel-Softmax relaxations, showing improved performance on synthetic and real-world benchmarks compared to BIC-scored baselines.
