arXiv:2606.30467v1 Announce Type: cross Abstract: We consider sparse multivariate stochastic systems that evolve in continuous time according to a causal mechanism and present methodology to recover the system's time-infinitesimal transition mechanism from mere cross-sectional data. This observational paradigm is motivated by applications such as gene expression analysis, where destructive experimental techniques may only allow recording data once over a cell's lifetime. Precisely, we assume the system follows a time-homogeneous diffusion process that has reached an equilibrium distribution at
The paper presents a significant advancement in methodology for causal inference in complex systems, building on recent trends in AI and statistical learning. It addresses a fundamental challenge in understanding dynamic systems from limited observational data.
Better non-parametric recovery of causal diffusion mechanisms could dramatically improve understanding and prediction in fields like biology, economics, and climate science, leading to more effective interventions. This is an important step towards enabling more sophisticated AI systems to infer causality from complex data.
The explicit ability to recover time-infinitesimal transition mechanisms from cross-sectional data, even in sparse multivariate stochastic systems, changes the landscape for observational studies. It offers a new tool for scientific discovery where only steady-state observations are possible.
