Distribution of Age of Information in the Erlang Loss System
Nail Akar, Sennur Ulukus
In this paper, we study the exact distributions of the age of information (AoI) and peak AoI (PAoI) in a bufferless setting in which time-stamped updates, or processed tasks, gener…
The Role of Feed-Forward Layers in Transformer Dynamics
Thomas Jacob Maranzatto, Semih Akkoc, Sennur Ulukus
We study the dynamical behavior of tokens in transformers from a control-theoretic perspective. Our model includes the feed-forward layer present after the self-attention mechanism…
GRASP: Generating, Revising, and Assessing for Strategic Planning with Agentic AI
Arunabh Srivastava, Mohammad A., Khojastepour +2
Large Language Models (LLMs) typically exhibit a performance profile where reliability degrades as task complexity increases. We address the challenge of generating high-quality na…
Private Information Retrieval With Arbitrary Privacy Requirements: Introduction and Capacity Results
Mohamed Nomeir, Shreya Meel, Sennur Ulukus
In this paper, we introduce the problem of private information retrieval (PIR) under arbitrary privacy requirements, in a graph-based storage system. This formulation is motivated…
Local Private Information Retrieval for Graph-Based Replicated Systems
Shreya Meel, Mohamed Nomeir, Sennur Ulukus
We rethink the definition of privacy in multi-server, graph-replicated private information retrieval (PIR) systems, by introducing a novel setting where the user's privacy is gover…
All-out Attack: Optimal Block Withholding Under Pay-Per-Share Scheme
Mustafa Doger, Sennur Ulukus
Classical Block Withholding (BWH) attacks have been extensively studied in block-dependent reward schemes, where pool members are compensated upon a block discovery within the pool…
