Explicit Rank Extractors and Subspace Designs via Function Fields, with Applications to Strong Blocking Sets
arXiv:2604.13431v2 Announce Type: replace Abstract: We give new explicit constructions of several fundamental objects in linear-algebraic pseudorandomness and combinatorics, including lossless rank extractors, weak subsp…
Don't Let AI Agents YOLO Your Files: Information and Control in Agent-Native Filesystems
arXiv:2604.13536v4 Announce Type: replace Abstract: AI coding agents regularly misuse their filesystem access, causing data corruption, loss, and leakage. We conduct the first systematic study of this problem through an …
Weighted NetKAT: A Programming Language For Quantitative Network Verification
arXiv:2604.13987v2 Announce Type: replace Abstract: We introduce weighted NetKAT, a domain-specific language for modeling and verifying quantitative network properties. The language is parametric on a semiring, enabling …
DiscoTrace: Representing and Comparing Answering Strategies of Humans and LLMs in Information-Seeking Question Answering
arXiv:2604.15140v2 Announce Type: replace Abstract: We introduce DiscoTrace, a method to identify the rhetorical strategies answerers use when responding to information-seeking questions. DiscoTrace represents answers as…
Why Fine-Tuning Encourages Hallucinations and How to Fix It
arXiv:2604.15574v2 Announce Type: replace Abstract: Large language models are prone to hallucinating factually incorrect statements. A key source of these errors is exposure to new factual information through supervised …
Global Attention with Linear Complexity for Exascale Generative Data Assimilation in Earth System Prediction
arXiv:2604.16590v2 Announce Type: replace Abstract: Accurate Earth system prediction requires state inference from incomplete observations, but conventional two-stage data assimilation (DA) is computationally prohibitive…
Agentic Large Language Models for Training-Free Neuro-Radiological Image Analysis
arXiv:2604.16729v2 Announce Type: replace Abstract: State-of-the-art large language models (LLMs) show high performance in general visual question answering. However, a fundamental limitation remains: current architectur…
The Topological Trouble With Transformers
arXiv:2604.17121v5 Announce Type: replace Abstract: Transformers encode structure in sequences via an expanding contextual history. However, their purely feedforward architecture fundamentally limits dynamic state tracki…
Reparameterization through Coverings and Topological Weight Priors
arXiv:2604.23804v2 Announce Type: replace Abstract: We generalise the reparameterization trick (RT) applied in variational autoencoders (VAEs) letting these have latent spaces of non-trivial topology - i.e. that of base …
Finding Shortest Reconfiguration Sequences on Independent Set Polytopes
arXiv:2604.24132v2 Announce Type: replace Abstract: We initiate the study of the shortest reconfiguration problem for independent sets under the adjacency relation derived from the independent set polytope. Given a graph…
Optimal UGV-UAV Cooperative Partitioning and Inspection of Shortest Paths
