Towards Reading Beyond Faces for Sparsity-aware 3D/4D Affect Recognition
In this paper, we present a sparsity-aware deep network for automatic 3D/4D facial expression recognition (FER). We first propose a novel augmentation […]
Non-Orthogonal Multiple Access and Network Slicing: Scalable Coexistence of eMBB and URLLC
The 5G systems feature three generic services: enhanced Mobile BroadBand (eMBB), massive Machine-Type Communications (mMTC) and Ultra-Reliable and Low-Latency Communications (URLLC). The […]
Passive RIS vs. Hybrid RIS
The reconfigurable intelligent surface (RIS) plays an important role in maintaining the connectivity in millimeter wave (mmWave) MIMO systems when the direct […]
Hybrid Bayesian-based Indoor Localization Mechanisms for Distributed Antenna Systems
This work proposes and evaluates a hybrid Bayesian-based localization method to estimate the position of a target node using received signal strength […]
