GRACE: Gated Refinement for Accurate Causal Edge Discovery in High-Dimensional Time Series

arXiv:2606.23880v1 Announce Type: new Abstract: From climate teleconnections to gene regulation, modern time-series datasets encompass tens or hundreds of interacting variables, making causal discovery increasingly challenging. Constraint-based methods offer statistical rigor but their nonlinear CI tests are infeasible at scale, while score-based alternatives avoid CI testing but require arbitrary thresholds to binarize continuous edge scores. We propose GRACE ($\textbf{G}$ated $\textbf{R}$efinement for $\textbf{A}$ccurate $\textbf{C}$ausal $\textbf{E}$dge discovery), which refines constraint-

Why this matters
Why now

The increasing complexity and scale of modern time-series datasets across various scientific domains necessitate more efficient and accurate causal discovery methods.

Why it’s important

Improved causal edge discovery in high-dimensional time series can accelerate scientific understanding, optimize complex systems, and inform better AI model development by revealing underlying relationships more precisely.

What changes

The proposed GRACE method offers a more scalable and accurate approach to identifying causal relationships in large datasets compared to existing constraint-based or score-based methods.
