arXiv:2606.07325v1 Announce Type: cross Abstract: We study the minimax rate of estimating a future value $\mu_{t_n+h}$ of a curve $t\mapsto\mu_t$ in the $2$-Wasserstein space $\mathcal{P}_2(\mathbb{R}^d)$ from finitely many noisy snapshots of its past, under an adiabatic bound $\|\nabla_t^k v\|\le\varepsilon$ on the $k$-th covariant derivative of the velocity field. Our central result is a unified temporal-spatial minimax lower bound: over regular, locally transport-rich subclasses, every estimator incurs $W_2$-risk with $M$-exponent $\gamma_d(k+1)/(k+1+\gamma_d)$, $\gamma_d=\min(1/d,1/2)$ ($M
The paper represents fundamental research in active inference and machine learning, aligning with the ongoing theoretical advancements in AI, especially concerning temporal-spatial data and mathematical rigor.
This research provides foundational mathematical tools for understanding and predicting dynamic systems, which is crucial for the development of more robust, efficient, and explainable AI models, particularly in areas requiring spatio-temporal reasoning.
The proposed minimax rate establishes theoretical limits for estimating smoothly-varying distributions in Wasserstein space, which can guide the development of new algorithms and models in AI and statistical learning, enabling more principled approaches to complex data analysis.
