Abstract
- Recently there were research works on multi-task estimation. However, there exists an issue that nodes may suffer from malicious attacks when sending data in the adversarial multi-task network environment. To address this issue, we propose a secure distributed information sharing algorithm based on attack detection. In our work, via determining an adaptive threshold, a distributed detection algorithm based on the correlation between tasks and a safe multi-task diffusion least mean square (SM-DLMS) algorithm are proposed, which not only reduce communication costs but also effectively decrease the impact of attacks. We also theoretically analyze the stability performance of the proposed SM-DLMS algorithm. Meanwhile, the robustness and effectiveness of the proposed algorithm under network-attacks are illustrated through numerical simulations. [ABSTRACT FROM AUTHOR]
