Stability and Performance Limits of Adaptive Primal-Dual Networks
Zaid J. Towfic, Ali H. Sayed
This work studies distributed primal-dual strategies for adaptation and learning over networks from streaming data. Two first-order methods are considered based on the Arrow-Hurwic…
A Neuron as a Signal Processing Device
Tao Hu, Zaid J. Towfic, Cengiz Pehlevan +2
A neuron is a basic physiological and computational unit of the brain. While much is known about the physiological properties of a neuron, its computational role is poorly understo…
Dictionary Learning over Distributed Models
Jianshu Chen, Zaid J. Towfic, Ali H. Sayed
In this paper, we consider learning dictionary models over a network of agents, where each agent is only in charge of a portion of the dictionary elements. This formulation is rele…
Adaptive Penalty-Based Distributed Stochastic Convex Optimization
Zaid J. Towfic, Ali H. Sayed
In this work, we study the task of distributed optimization over a network of learners in which each learner possesses a convex cost function, a set of affine equality constraints,…
Excess-Risk of Distributed Stochastic Learners
Zaid J. Towfic, Jianshu Chen, Ali H. Sayed
This work studies the learning ability of consensus and diffusion distributed learners from continuous streams of data arising from different but related statistical distributions.…
On Distributed Online Classification in the Midst of Concept Drifts
Zaid J. Towfic, Jianshu Chen, Ali H. Sayed
In this work, we analyze the generalization ability of distributed online learning algorithms under stationary and non-stationary environments. We derive bounds for the excess-risk…
