Analysing the Data-Driven Approach of Dynamically Estimating Positioning Accuracy

no code implementations20 Nov 2020 Grigorios G. Anagnostopoulos, Alexandros Kalousis

More specifically, with the use of a public LoRaWAN dataset, the current work analyses: the repartition of the available training set between the tasks of determining the location estimates and the DAE, the concept of selecting a subset of the most reliable estimates, and the impact that the spatial distribution of the data has to the accuracy of the DAE.
