DoRF++: Spherical Representation Learning over Doppler Radiance Fields for Robust Wi-Fi Sensing
Navid Hasanzadeh, Shahrokh Valaee
Motivated by the IEEE 802.11bf effort to standardize advanced WLAN sensing, interest in Wi-Fi Channel State Information (CSI) for passive, device-free, and privacy-preserving activ…
MORIC: CSI Delay-Doppler Decomposition for Robust Wi-Fi-based Human Activity Recognition
Navid Hasanzadeh, Shahrokh Valaee
The newly established IEEE 802.11bf Task Group aims to amend the WLAN standard to support advanced sensing applications such as human activity recognition (HAR). Although studies h…
Maximizing Connectivity of Uplink RIS-Assisted UAV Networks
Mohammed Saif, Shahrokh Valaee
In this paper, we present a new approach for unmanned aerial vehicle (UAV) positioning and reconfigurable intelligent surface (RIS) partitioning to enhance connectivity of uplink R…
Extending Kernel Trick to Influence Functions
Zhenhuan Sun, Shahrokh Valaee
In this paper, we present a dual representation of the influence functions, whose computational complexity scales with dataset size rather than model size. Both analytically and ex…
Doppler Radiance Field-Guided Antenna Selection for Improved Generalization in Multi-Antenna Wi-Fi-based Human Activity Recognition
Navid Hasanzadeh, Shahrokh Valaee
With the IEEE 802.11bf Task Group introducing amendments to the WLAN standard for advanced sensing, interest in using Wi-Fi Channel State Information (CSI) for remote sensing has s…
DoRF: Doppler Radiance Fields for Robust Human Activity Recognition Using Wi-Fi
Navid Hasanzadeh, Shahrokh Valaee
