Speaker Recognition Using Isomorphic Graph Attention Network Based Pooling on Self-Supervised Representation
Zirui Ge, Xinzhou Xu, Haiyan Guo +2
The emergence of self-supervised representation (i.e., wav2vec 2.0) allows speaker-recognition approaches to process spoken signals through foundation models built on speech data.…
The Graph feature fusion technique for speaker recognition based on wav2vec2.0 framework
Zirui Ge, Haiyan Guo, Zhen Yang
Pre-trained wav2vec2.0 model has been proved its effectiveness for speaker recognition. However, current feature processing methods are focusing on classical pooling on the output…
Joint Reconfigurable Intelligent Surface Location and Passive Beamforming Optimization for Maximizing the Secrecy-Rate
Haiyan Guo, Zhen Yang, Yulong Zou +3
The physical layer security (PLS) is investigated for reconfigurable intelligent surface (RIS) assisted wireless networks, where a source transmits its confidential information to…
Universal Graph Filter Design based on Butterworth, Chebyshev and Elliptic Functions
Zirui Ge, Haiyan Guo, Tingting Wang +1
