Asynchronous Adaptation and Learning Over Networks—Part III: Comparison Analysis

In Part II of this paper, also in this issue, we carried out a detailed mean-square-error analysis of the performance of asynchronous adaptation and learning over networks under a fairly general model for asynchronous events including random topologies, ra ...

Asynchronous Adaptation and Learning Over Networks—Part II: Performance Analysis

Ali H. Sayed

In Part I of this paper, also in this issue, we introduced a fairly general model for asynchronous events over adaptive networks including random topologies, random link failures, random data arrival times, and agents turning on and off randomly. We perfor ...

Asynchronous Adaptation and Learning Over Networks—Part I: Modeling and Stability Analysis

Ali H. Sayed

In this work and the supporting Parts II and III of this paper, also in the current issue, we provide a rather detailed analysis of the stability and performance of asynchronous strategies for solving distributed optimization and adaptation problems over n ...

Continuous-Time Trajectory Estimation for Event-based Vision Sensors

Davide Scaramuzza

Event-based vision sensors, such as the Dynamic Vision Sensor (DVS), do not output a sequence of video frames like standard cameras, but a stream of asynchronous events. An event is triggered when a pixel detects a change of brightness in the scene. An eve ...

Performance analysis of multitask diffusion adaptation over asynchronous networks

Ali H. Sayed, Roula Nassif

The multitask diffusion LMS algorithm is an efficient strategy to address distributed estimation problems that are multitask-oriented in the sense that the optimum parameter vector may not be the same for every cluster of nodes. In this work, we explore th ...

Synchronizing Code Execution on Ultra-Low-Power Embedded Multi-Channel Signal Analysis Platforms

David Atienza Alonso, Andreas Peter Burg, Giovanni Ansaloni, Ruben Braojos Lopez, Jeremy Hugues-Felix Constantin, Ahmed Yasir Dogan

Embedded biosignal analysis involves a considerable amount of parallel computations, which can be exploited by employing low-voltage and ultra-low-power (ULP) parallel computing architectures. By allowing data and instruction broadcasting, single instructi ...

Asynchronous diffusion adaptation over networks

Ali H. Sayed

This work studies the asynchronous behavior of diffusion adaptation strategies for distributed optimization over networks. Under the assumed model, agents in the network may stop updating their estimates or may stop exchanging information at random times. ...

Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...

How to Allocate Tasks Asynchronously

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Asynchronous task allocation is a fundamental problem in distributed computing in which p asynchronous processes must execute a set of m tasks. Also known as write-all or do-all, this problem been studied extensively, both independently and as a key buildi ...
