Jaccard analysis and LASSO-based feature selection for location fingerprinting with limited computational complexity
Caifa Zhou, Andreas Wieser
We propose an approach to reduce both computational complexity and data storage requirements for the online positioning stage of a fingerprinting-based indoor positioning system (F…
WiFi based trajectory alignment, calibration and easy site survey using smart phones and foot-mounted IMUs
Yang Gu, Caifa Zhou, Andreas Wieser +1
Foot-mounted inertial positioning (FMIP) can face problems of inertial drifts and unknown initial states in real applications, which renders the estimated trajectories inaccurate a…
Joint Positioning and Radio Map Generation Based on Stochastic Variational Bayesian Inference for FWIPS
Caifa Zhou, Yang Gu
Fingerprinting based WLAN indoor positioning system (FWIPS) provides a promising indoor positioning solution to meet the growing interests for indoor location-based services (e.g.,…
Application of backpropagation neural networks to both stages of fingerprinting based WIPS
Caifa Zhou, Andreas Wieser
We propose a scheme to employ backpropagation neural networks (BPNNs) for both stages of fingerprinting-based indoor positioning using WLAN/WiFi signal strengths (FWIPS): radio map…
