研究人员开发了一种从时间序列数据直接估计薛定谔桥（SB）漂移的新方法。该方法通过关注漂移公式本身，将统计误差与其他误差来源隔离开来，从而绕过了复杂的迭代求解器。该研究提供了理论保证，包括有限样本界和可实现近乎最优性能的自适应带宽选择器。 AI
影响 引入了一种新的统计估计技术，该技术有可能应用于生成模型或扩散模型。

Schrödinger Bridge时间序列漂移的直接估计：有限样本、渐近和自适应保证
arXiv:2605.05432v1 Announce Type: cross Abstract: We study nonparametric estimation of Schr\"odinger bridge (SB) drifts from i.i.d.\ data observed on a single time interval. Starting from the conditional-ratio form of the Schr\"odinger bridge time-series (SBTS) drift formula, we …

We study nonparametric estimation of Schrödinger bridge (SB) drifts from i.i.d.\ data observed on a single time interval. Starting from the conditional-ratio form of the Schrödinger bridge time-series (SBTS) drift formula, we analyze a direct Nadaraya--Watson plug-in estimator bu…
