“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...
【正确】There is a single unit (neuron) in the output layer. 【解释】This is correct. The neural network outputs a single number between 0 and 1. 【正确】The output of the model can be interpreted as the probability that the handwritten image is of the number one "1". ...
