Primal-Dual Strategy (PDS) for Composite Optimization Over Directed graphs
Sajad Zandi, Mehdi Korki
We investigate the distributed multi-agent sharing optimization problem in a directed graph, with a composite objective function consisting of a smooth function plus a convex (poss…
Markovian Block Sparse Signal Detection Using One Bit Measurements
Alireza Hariri, Hadi Zayyani, Mehdi Korki
This paper presents a novel sparse signal detection scheme designed for a correlated Markovian Bernoulli-Gaussian sparse signal model, which can equivalently be viewed as a block s…
Double-Private Distributed Estimation Algorithm Using Differential Privacy and a Key-Like Proportionate Matrix with Its Performance Analysis
Mehdi Korki, Fatemehsadat Hosseiniamin, Hadi Zayyani +1
In this brief, we present an enhanced privacy-preserving distributed estimation algorithm, referred to as the ``Double-Private Algorithm," which combines the principles of both dif…
Second-Order Nonlinearity Estimated and Compensated Diffusion LMS Algorithm: Theoretical Upper Bound, Cramer-Rao Lower bound, and Convergence Analysis
Hadi Zayyani, Mehdi Korki
In this paper, an algorithm for estimation and compensation of second-order nonlinearity in wireless sensor setwork (WSN) in distributed estimation framework is proposed. First, th…
Diffusion LMS for Distributed Estimation over Wireless Networks with Inter-Node Interference Perturbation
Mohammadjavad Mirzazadeh Moallem, Mehdi Korki
In this paper, we investigate the diffusion least mean square (DLMS) algorithm over fading channel, where in addition to channel noise and path-loss the inter-node-interference (IN…
Weighted diffusion LMP algorithm for distributed estimation in non-uniform noise conditions
H. Zayyani, M. Korki
This letter presents an improved version of diffusion least mean ppower (LMP) algorithm for distributed estimation. Instead of sum of mean square errors, a weighted sum of mean squ…
