arXiv:2606.03227v1 Announce Type: new Abstract: Causal discovery with instantaneous effects in multivariate time series is challenging, as the instantaneous structure must be acyclic. Prior methods enforce this by either separating instantaneous and lagged estimation into multi-stage pipelines or imposing algebraic acyclicity constraints via complex augmented Lagrangian optimization, both of which incur high computational cost. In this work, we propose a different approach: we learn a differentiable permutation of variables using the Gumbel--Sinkhorn operator and triangularize the instantaneou
The paper addresses a long-standing computational challenge in causal discovery for time series, indicating ongoing foundational research in AI's ability to model complex dynamic systems.
Improved causal discovery methods are critical for developing more robust, interpretable, and generalizable AI systems, moving beyond correlation to understanding underlying mechanisms in real-world data.
This work introduces a more computationally efficient and differentiable approach to learning temporal causal structures, which could accelerate progress in AI applications requiring accurate causal inference.
