图形化状态空间模型

Graphical State Space Model

Shaolin Lü

摘要:

针对一类非线性状态空间模型的实时最优估计问题,提出了一种新的框架--图形状态空间模型。通过将这类系统模型离散为一个扩展卡尔曼滤波器无法求解的方程,因子图优化在某些情况下可以优于扩展卡尔曼滤波器。一个简单的非线性的例子来证明这个框架的效率。

英文摘要:

In this paper, a new framework, named as graphical state space model, is proposed for the real time optimal estimation of a class of nonlinear state space model. By discretizing this kind of system model as an equation which can not be solved by Extended Kalman filter, factor graph optimization can outperform Extended Kalman filter in some cases. A simple nonlinear example is given to demonstrate the efficiency of this framework.
