報告摘要：
With theincreasing demand for location-based service, WiFi-based localization hasbecome one of the most popular methods due to the wide deployment of WiFi andits relatively low cost. In this talk, we first present a quick review of deeplearning based indoor fingerprinting, and then will focus on deep Gaussian processbased indoor radio map construction and location estimation system. Receivedsignal strength (RSS) samples, as well earth magnetic field readings, are usedto generate accurate and fine-grained radio maps with confidence intervalsusing deep Gaussian process, while the model parameters are optimized with anoffline Bayesian training method. Utilizing the maps, an LSTM based locationprediction model is pre-trained with the artificial trajectory data and thenfine-tuned with the signal measurements collected by the mobile device to belocalized. Our extensive experiments demonstrate the excellent performance ofthe proposed system.
