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…
Pedestrian Positioning Using WiFi Fingerprints and a Foot-mounted Inertial Sensor
Yang Gu, Caifa Zhou, Andreas Wieser +1
Foot-mounted inertial positioning (FMIP) and fingerprinting based WiFi indoor positioning (FWIP) are two promising solutions for indoor positioning. However, FMIP suffers from accu…
Fast Radio Map Construction and Position Estimation via Direct Mapping for WLAN Indoor Localization System
Caifa Zhou, Andreas Wieser, Xuezhi Tan
The main limitation that constrains the fast and comprehensive application of Wireless Local Area Network (WLAN) based indoor localization systems with Received Signal Strength (RS…
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…
