迭代协方差逼近下模型不确定性下的参数估计

Parameter Estimation Under Model Uncertainties by Iterative Covariance Approximation

Oliver Lang, Michael Lunglmayr, Mario Huemer

摘要:

我们提出了一种新的迭代算法来估计一个确定的,但未知的参数向量的存在模型的不确定性。该迭代算法基于系统模型,其中总噪声项描述测量噪声和由模型不确定性引起的噪声。该总噪声项是真实参数向量的函数,允许迭代算法。所提出的算法可以应用于结构化以及非结构化的模型,它优于现有技术的算法,广泛的应用。

英文摘要:

We propose a novel iterative algorithm for estimating a deterministic but unknown parameter vector in the presence of model uncertainties. This iterative algorithm is based on a system model where an overall noise term describes both, the measurement noise and the noise resulting from the model uncertainties. This overall noise term is a function of the true parameter vector, allowing for an iterative algorithm. The proposed algorithm can be applied on structured as well as unstructured models and it outperforms prior art algorithms for a broad range of applications.
