Age of Information under Energy Replenishment Constraints Bacınoğlu, Baran Tan; Ceran, Elif Tugce; Uysal, Elif (2015-02-06) We consider managing the freshness of status updates sent from a source (such as a sensor) to a monitoring node. The time-varying availability of energy at the sender limits the rate of update packet transmissions. At any time, the age of information is defined as the amount of time since the most recent update was successfully received. An offline solution that minimizes not only the time average age, but also the peak age for an arbitrary energy replenishment profile is derived. The related decision probl...
Age of information and unbiased federated learning in energy harvesting error-prone channels Çakır, Zeynep; Ceran Arslan, Elif Tuğçe; Department of Electrical and Electronics Engineering (2022-8-29) Federated learning is a communication-efficient and privacy-preserving learning tech nique for collaborative training of machine learning models on vast amounts of data produced and stored locally on the distributed users. In this thesis, unbiased feder ated learning methods that achieve a similar convergence as state-of-the-art federated learning methods in scenarios with various constraints like error-prone channel or in termittent energy availability are investigated. In addition, a prevalent metric call...
Age-Optimal Status Updating with an Energy Harvesting Sender Bacınoğlu, Baran Tan; Uysal, Elif (null; 2017-02-13)
Age-Optimal Channel Coding Blocklength for an M/G/1 Queue with HARQ Sac, Hakan; Bacinoglu, Tan; Uysal, Elif; Durisi, Giuseppe (2018-08-24) We consider a communication system in which a source transmits information updates to a destination node through a binary erasure channel (BEC). When a packet containing an information update, which consists of a fixed number of information bits, arrives at the transmitter, it gets queued in a buffer, to be encoded and sent over the channel. Before transmitting a packet, the transmitter selects a channel coding blocklength n and then uses an automatic repeat request (ARQ) protocol, whereby packets that are ...
Age and response bias: evidence from the strength-based mirror effect. Criss, AH; Aue, W; Kılıç Özhan, Aslı (SAGE Publications, 2014-10-01) Performance in episodic memory is determined both by accurate retrieval from memory and by decision processes. A substantial body of literature suggests slightly poorer episodic memory accuracy for older than younger adults; however, age-related changes in the decision mechanisms in memory have received much less attention. Response bias, the willingness to endorse an item as remembered, is an important decision factor that contributes to episodic memory performance, and therefore understanding age-related ...
