From Toxic to Trustworthy: Using Self-Distillation and Semi-supervised Methods to Refine Neural Networks

AAAI 2024technical

Despite the tremendous success of deep neural networks (DNNs) across various fields, their susceptibility to potential backdoor attacks seriously threatens their application security, particularly in safety-critical or security-sensitive ones. Given this growing threat, there is a pressing need for…

Joint group power allocation and prebeamforming for joint spatial-division multiplexing in multiuser massive MIMO systems

ICASSP 2015accepted

We investigate the joint optimization of the group power allocation and prebeamformer for joint spatial division and multiplexing (JSDM) in massive MIMO downlink systems. In contrast with the approximated block diagonalization (ABD) prebeamformer which is derived by heuristic method in the original…
