New algorithm bypasses optimization for scalable causal discovery

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed a new method for causal discovery that bypasses the need for complex, non-convex optimization. The Score-Schur Topological Sort (SSTS) algorithm extracts topological order directly from generative models by leveraging the geometric properties of the score function. This approach reframes causal discovery from a constrained optimization problem to a statistical estimation challenge, enabling analysis on non-linear graphs with up to 1000 dimensions. AI

    Optimization-Free Topological Sort for Causal Discovery via the Schur Complement of Score Jacobians

    arXiv:2604.25295v1 Announce Type: new Abstract: Continuous causal discovery typically couples representation learning with structural optimization via non-convex acyclicity penalties, which subjects solvers to local optima and restricts scalability in high-dimensional regimes. We…

    Optimization-Free Topological Sort for Causal Discovery via the Schur Complement of Score Jacobians

    Continuous causal discovery typically couples representation learning with structural optimization via non-convex acyclicity penalties, which subjects solvers to local optima and restricts scalability in high-dimensional regimes. We propose a decoupled paradigm that shifts the ca…
