arXiv:2603.14667v1 Announce Type: cross Abstract: Magnetic resonance imaging (MRI) super-resolution (SR) methods that computationally enhance low-resolution acquisitions to approximate high-resolution quality offer a compelling alternative to expensive high-field scanners. In this work we investigate an elucidated diffusion model (EDM) framework for brain MRI SR and compare two U-Net backbone architectures: (i) a full 3D convolutional […]
Universe Routing: Why Self-Evolving Agents Need Epistemic Control
arXiv:2603.14799v1 Announce Type: cross Abstract: A critical failure mode of current lifelong agents is not lack of knowledge, but the inability to decide how to reason. When an agent encounters “Is this coin fair?” it must recognize whether to invoke frequentist hypothesis testing or Bayesian posterior inference – frameworks that are epistemologically incompatible. Mixing them […]
A Dual-Path Generative Framework for Zero-Day Fraud Detection in Banking Systems
arXiv:2603.13237v1 Announce Type: new Abstract: High-frequency banking environments face a critical trade-off between low-latency fraud detection and the regulatory explainability demanded by GDPR. Traditional rule-based and discriminative models struggle with “zero-day” attacks due to extreme class imbalance and the lack of historical precedents. This paper proposes a Dual-Path Generative Framework that decouples real-time anomaly detection […]
Querying Everything Everywhere All at Once: Supervaluationism for the Agentic Lakehouse
arXiv:2603.13380v1 Announce Type: cross Abstract: Agentic analytics is turning the lakehouse into a multi-version system: swarms of (human or AI) producers materialize competing pipelines in data branches, while (human or AI) consumers need answers without knowing the underlying data life-cycle. We demonstrate a new system that answers questions across branches rather than at a single […]
AI-Driven Predictive Maintenance with Real-Time Contextual Data Fusion for Connected Vehicles: A Multi-Dataset Evaluation
arXiv:2603.13343v1 Announce Type: cross Abstract: Most vehicle predictive maintenance systems rely exclusively on internal diagnostic signals and are validated on deterministic synthetic data, limiting the credibility of reported metrics. This paper presents a simulation-validated proof-of-concept framework for V2X-augmented predictive maintenance, integrating on-board sensor streams with external contextual signals — road quality, weather, traffic density, and […]
Nudging Hidden States: Training-Free Model Steering for Chain-of-Thought Reasoning in Large Audio-Language Models
arXiv:2603.14636v1 Announce Type: cross Abstract: Chain-of-thought (CoT) prompting has been extended to large audio-language models (LALMs) to elicit reasoning, yet enhancing its effectiveness without training remains challenging. We study inference-time model steering as a training-free approach to improve LALM reasoning. We introduce three strategies using diverse information sources and evaluate them across four LALMs and […]
Aura: Universal Multi-dimensional Exogenous Integration for Aviation Time Series
arXiv:2603.05092v2 Announce Type: replace-cross Abstract: Time series forecasting has witnessed an increasing demand across diverse industrial applications, where accurate predictions are pivotal for informed decision-making. Beyond numerical time series data, reliable forecasting in practical scenarios requires integrating diverse exogenous factors. Such exogenous information is often multi-dimensional or even multimodal, introducing heterogeneous interactions that unimodal time […]
WaveComm: Lightweight Communication for Collaborative Perception via Wavelet Feature Distillation
arXiv:2603.13365v1 Announce Type: cross Abstract: In multi-agent collaborative sensing systems, substantial communication overhead from information exchange significantly limits scalability and real-time performance, especially in bandwidth-constrained environments. This often results in degraded performance and reduced reliability. To address this challenge, we propose WaveComm, a wavelet-based communication framework that drastically reduces transmission loads while preserving sensing performance […]
Malicious Agent Skills in the Wild: A Large-Scale Security Empirical Study
arXiv:2602.06547v2 Announce Type: replace-cross Abstract: Third-party agent skills extend LLM-based agents with instruction files and executable code that run on users’ machines. Skills execute with user privileges and are distributed through community registries with minimal vetting, but no ground-truth dataset exists to characterize the resulting threats. We construct the first labeled dataset of malicious agent […]
Do Mixed-Vendor Multi-Agent LLMs Improve Clinical Diagnosis?
arXiv:2603.04421v2 Announce Type: replace-cross Abstract: Multi-agent large language model (LLM) systems have emerged as a promising approach for clinical diagnosis, leveraging collaboration among agents to refine medical reasoning. However, most existing frameworks rely on single-vendor teams (e.g., multiple agents from the same model family), which risk correlated failure modes that reinforce shared biases rather than […]
Hide and Seek: Investigating Redundancy in Earth Observation Imagery
arXiv:2603.13524v1 Announce Type: cross Abstract: The growing availability of Earth Observation (EO) data and recent advances in Computer Vision have driven rapid progress in machine learning for EO, producing domain-specific models at ever-increasing scales. Yet this progress risks overlooking fundamental properties of EO data that distinguish it from other domains. We argue that EO data […]
Beyond Linearity in Attention Projections: The Case for Nonlinear Queries
arXiv:2603.13381v1 Announce Type: cross Abstract: Recent algebraic analysis shows that in decoder-only and encoder-only transformers, the Query projection $W_Q$ may be set to identity without noticeable performance deterioration. This is possible because attention depends on $X$ only through the products $XW_Q, XW_K, XW_V$, allowing basis transformations to be absorbed by adjacent layers and propagated through […]
