新界限改进线性系统辨识的参数误差估计

作者 PulseAugur 编辑部 · [2 个来源] · 2026-04-23 04:25

研究人员发现当前最先进的线性系统辨识界限存在差异，表明它们可能将参数误差夸大了与系统状态维度相关的因子。他们提出了一种新颖的二阶分解来锐化这些界限，引入了一个精确反映中心极限定理缩放的矩阵值鞅。这项工作为稳定和多轨迹设置产生了改进的有限样本界限，与最优速率非常接近。 AI

影响精炼了线性动力系统中参数估计的理论理解，可能影响相关人工智能应用中的模型鲁棒性和准确性。

CLT-Optimal 参数线性系统辨识误差界限

There has been remarkable progress over the past decade in establishing finite-sample, non-asymptotic bounds on recovering unknown system parameters from observed system behavior. Surprisingly, however, we show that the current state-of-the-art bounds do not accurately capture th…
