摘要:

我们介绍了一种分布式、协作的框架和方法,用于分布式代理网络中的贝叶斯估计与控制。该框架结合了时间变化的全局和局部状态的联合估计与信息寻求控制,以优化代理的行为。它适用于非线性和非高斯问题,特别是位置感知网络。对于协作估计,采用信念传播消息传递与共识的结合。对于协作控制,通过梯度上升最大化所有状态的负后验联合熵。估计层以概率分布的样本表示形式为控制层提供概率信息。仿真结果展示了代理的智能行为和在同时进行自我定位和目标跟踪问题中的出色估计性能。在仅有一个锚点的协作定位场景中,移动代理可以在短时间内完成自身定位,其精度高于所进行的距离测量精度。

英文摘要:

We introduce a distributed, cooperative framework and method for Bayesian estimation and control in decentralized agent networks. Our framework combines joint estimation of time-varying global and local states with information-seeking control optimizing the behavior of the agents. It is suited to nonlinear and non-Gaussian problems and, in particular, to location-aware networks. For cooperative estimation, a combination of belief propagation message passing and consensus is used. For cooperative control, the negative posterior joint entropy of all states is maximized via a gradient ascent. The estimation layer provides the control layer with probabilistic information in the form of sample representations of probability distributions. Simulation results demonstrate intelligent behavior of the agents and excellent estimation performance for a simultaneous self-localization and target tracking problem. In a cooperative localization scenario with only one anchor, mobile agents can localize themselves after a short time with an accuracy that is higher than the accuracy of the performed distance measurements.
