On the benefits of diffusion cooperation for distributed optimization and learning
Jianshu Chen,Ali H. Sayed +1 more
TL;DR: It is shown that, for sufficiently small step-sizes, the limiting behavior of the network is mainly influenced by the right-eigenvector of the combination policy corresponding to the single eigenvalue at one.
Journal ArticleDOI
Carrier Recovery Enhancement for Maximum-Likelihood Doppler Shift Estimation in Mars Exploration Missions
TL;DR: A Maximum Likelihood approach is proposed that takes into account the power in the data tones to enhance carrier recovery, and improve the estimation performance by up to 3 dB, which is expected to help maintain reliable communication from the spacecraft to Earth.
Journal ArticleDOI
Signal Processing Theory and Methods [In the Spotlight]
TL;DR: Solving estimation and tracking problems over cognitive networks that requires optimizing certain global cost functions in a distributed manner is discussed.
Proceedings ArticleDOI
Network Classifiers Based on Social Learning
TL;DR: In this paper, the authors proposed a new way of combining independently trained classifiers over space and time, which is able to improve prediction performance over time with unlabeled data, and they showed that this strategy results in consistent learning with high probability.
