Abstract

Automated uncertainty propagation is a powerful tool that allows to focus on the interpretation and analysis of the uncertainty rather than on its calculation. A teaching concept based on the use of a software toolbox for automated uncertainty propagation have been previously developed. This work introduces Bayesian Linear Minimum Mean Square Estimation with automated uncertainty propagation, proposing an extension of the teaching concept, towards the use of uncertainty in sensor and data fusion. The toolbox provides the methods linearization, Unscented Transform and Monte Carlo for uncertainty propagation. Since the code for all three variants is essentially equivalent and compact, concepts as the Extended Kalman Filter and the Unscented Kalman Filter are easily implemented following the same approach as for the already introduced uncertainty quantification. The proposed approach simplifies the integration of advanced topics such as late fusion or posterior estimation of previous states in measurement science education.
使用自动不确定性传播的高级信号处理-一种教育方法
自动化不确定性传播是一个强大的工具,它允许专注于不确定性的解释和分析,而不是其计算。一种基于使用软件工具箱进行自动不确定性传播的教学概念已经被开发出来。这项工作介绍了具有自动不确定性传播的贝叶斯线性最小均方估计,提出了对不确定性在传感器和数据融合中的应用的教学概念的扩展。工具箱提供了用于不确定性传播的线性化、Unscented变换和蒙特卡罗方法。由于所有三种变体的代码本质上是等效的和紧凑的,因此扩展卡尔曼滤波器和无气味卡尔曼滤波器的概念很容易按照与已经引入的不确定性量化相同的方法实现。该方法简化了测量科学教育中后期融合或前态后验估计等高级课题的整合。
