Chained Recursive Language Models for Multi-Iteration Reasoning
Purbesh Mitra, Sennur Ulukus
Long context reasoning in large language models (LLMs) is usually constrained by the fact that a single inference trajectory has to simultaneously explore the context, store interm…
Dependency Triad: A Metric to Quantify the Dependencies Between Attributes for Local Differential Privacy
Sandaru Jayawardana, Sennur Ulukus, Ming Ding +1
Collecting multidimensional user data is essential for extracting rich insights across various applications. Local Differential Privacy (LDP) has emerged as a de facto standard for…
Squeezing the Most Out of Preemption for AoI Minimization: Single-source Case
Nail Akar, Mohammad Moltafet, Sennur Ulukus +2
In this work, we study a single-source single-server continuous-time status update system where the updates arrive according to a Poisson process and update service times are gener…
On the Diverse Dynamical Behaviors Arising in Deep Linear Transformers
Sixu Li, Thomas Jacob Maranzatto, Jan Peszek +5
We study the inference-time behavior of deep linear encoder-only transformers through the lens of interacting particle systems. In this perspective, tokens are modeled as particles…
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…
Dual-Regime Absorbing Markov Chain Theory in Remote Estimation: Age-Minimizing Push Policies
Ismail Cosandal, Sennur Ulukus, Nail Akar
For a remote estimation system, we study the optimization of age of incorrect information (AoII), which is a recently proposed semantic-aware information freshness metric. In parti…
