利用扩散图进行无线定位

Wireless localization with diffusion maps

Amin Ghafourian, Orestis Georgiou, Edmund Barter, Thilo Gross

摘要:

在无线定位匹配问题(WLMP)中,挑战是基于由设备进行的无线信号测量将设备与一组候选位置进行匹配。无线信号测量中固有的噪声使这一挑战变得更加复杂。在这里,我们建议使用扩散映射,流形学习技术,以获得嵌入的位置和设备坐标在一个空间,使坐标比较和可靠的评估分配质量在非常低的计算成本。我们表明,映射是强大的噪声和使用扩散地图允许在现实环境中的准确匹配。这表明基于扩散图的方法可以显著提高应用中无线定位的准确性。

英文摘要:

In the Wireless Localization Matching Problem (WLMP) the challenge is to match pieces of equipment with a set of candidate locations based on wireless signal measurements taken by the pieces of equipment. This challenge is complicated by the noise that is inherent in wireless signal measurements. Here we propose the use of diffusion maps, a manifold learning technique, to obtain an embedding of positions and equipment coordinates in a space that enables coordinate comparison and reliable evaluation of assignment quality at very low computational cost. We show that the mapping is robust to noise and using diffusion maps allows for accurate matching in a realistic setting. This suggests that the diffusion-map-based approach could significantly increase the accuracy of wireless localization in applications.
