部分观测马尔可夫过程约束状态估计的变量分裂方法

Variable Splitting Methods for Constrained State Estimation in Partially Observed Markov Processes

Rui Gao, Filip Tronarp, Simo Särkkä

摘要:

在本文中,我们提出了一类有效的,准确的,和一般的方法来解决状态估计问题的等式和不等式约束。该方法是基于变量分裂和部分观测马尔可夫过程的最新发展。我们首先提出了基于变量分裂的广义框架,然后开发有效的方法来解决框架中出现的状态估计子问题。这些子问题的解决方案可以通过利用模型的马尔可夫结构来有效地进行,这在所谓的贝叶斯过滤和平滑方法中是经典的。数值实验表明,我们的方法优于传统的最优化方法的计算成本以及估计性能。

英文摘要:

In this paper, we propose a class of efficient, accurate, and general methods for solving state-estimation problems with equality and inequality constraints. The methods are based on recent developments in variable splitting and partially observed Markov processes. We first present the generalized framework based on variable splitting, then develop efficient methods to solve the state-estimation subproblems arising in the framework. The solutions to these subproblems can be made efficient by leveraging the Markovian structure of the model as is classically done in so-called Bayesian filtering and smoothing methods. The numerical experiments demonstrate that our methods outperform conventional optimization methods in computation cost as well as the estimation performance.
