Version Age of Information in Clustered Gossip Networks
Baturalp Buyukates, Melih Bastopcu, Sennur Ulukus
We consider a network consisting of a single source and receiver nodes that are grouped into equal-sized clusters. We use cluster heads in each cluster to facilitate communicat…
Gossiping with Binary Freshness Metric
Melih Bastopcu, Baturalp Buyukates, Sennur Ulukus
We consider the binary freshness metric for gossip networks that consist of a single source and end-nodes, where the end-nodes are allowed to share their stored versions of the…
Age of Gossip in Networks with Community Structure
Baturalp Buyukates, Melih Bastopcu, Sennur Ulukus
We consider a network consisting of a single source and receiver nodes that are grouped into equal size communities, i.e., clusters, where each cluster includes nodes a…
Gradient Coding with Dynamic Clustering for Straggler-Tolerant Distributed Learning
Baturalp Buyukates, Emre Ozfatura, Sennur Ulukus +1
Distributed implementations are crucial in speeding up large scale machine learning applications. Distributed gradient descent (GD) is widely employed to parallelize the learning t…
Timely Communication in Federated Learning
Baturalp Buyukates, Sennur Ulukus
We consider a federated learning framework in which a parameter server (PS) trains a global model by using clients without actually storing the client data centrally at a cloud…
Gradient Coding with Dynamic Clustering for Straggler Mitigation
Baturalp Buyukates, Emre Ozfatura, Sennur Ulukus +1
In distributed synchronous gradient descent (GD) the main performance bottleneck for the per-iteration completion time is the slowest \textit{straggling} workers. To speed up GD it…
Age-Based Coded Computation for Bias Reduction in Distributed Learning
Emre Ozfatura, Baturalp Buyukates, Deniz Gunduz +1
Coded computation can be used to speed up distributed learning in the presence of straggling workers. Partial recovery of the gradient vector can further reduce the computation tim…
Selective Encoding Policies for Maximizing Information Freshness
Melih Bastopcu, Baturalp Buyukates, Sennur Ulukus
An information source generates independent and identically distributed status update messages from an observed random phenomenon which takes distinct values based on a given p…
Age of Information with Gilbert-Elliot Servers and Samplers
Baturalp Buyukates, Sennur Ulukus
We study age of information in a status updating system that consists of a single sampler, i.e., source node, that sends time-sensitive status updates to a single monitor node thro…
Optimal Selective Encoding for Timely Updates
Melih Bastopcu, Baturalp Buyukates, Sennur Ulukus
We consider a system in which an information source generates independent and identically distributed status update packets from an observed phenomenon that takes possible valu…
Timely Distributed Computation with Stragglers
Baturalp Buyukates, Sennur Ulukus
We consider a status update system in which the update packets need to be processed to extract the embedded useful information. The source node sends the acquired information to a…
Age of Information Scaling in Large Networks with Hierarchical Cooperation
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
Given randomly located source-destination (S-D) pairs on a fixed area network that want to communicate with each other, we study the age of information with a particular focus…
Age of Information in Multicast Networks with Multiple Update Streams
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
We consider the age of information in a multicast network where there is a single source node that sends time-sensitive updates to receiver nodes. Each status update is one of…
Age of Information in Multihop Multicast Networks
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
We consider the age of information in a multihop multicast network where there is a single source node sending time-sensitive updates to end nodes, and denotes the number…
Age of Information Scaling in Large Networks
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
We study age of information in a multiple source-multiple destination setting with a focus on its scaling in large wireless networks. There are nodes that are randomly paired w…
