In Chapter 1, we present fundamental concepts, on which the works are based, and provide an overview of this dissertation. In Part I, we develop two novel adaptive algorithms to solve machine learning problems, derive their theoretical convergence, conduct numerical experiment on binary ...
“Using machine learning, we created smart anchor selection algorithms that detect the (non) line-of-sight between UWB anchors and the mobile devices that are being tracked. Building on that knowledge, the ranging quality is estimated, and ranging errors are corrected. Since our approach also com...
