Conservative Proxy Prompting for Reliable Frozen Vision–Language Models with Missing Modalities

This paper proposes Conservative Proxy Prompting (CPP), a parameter-efficient framework that enhances the reliability of frozen vision-language models under missing modalities by constructing feature-space proxy representations and conservatively regulating their contribution to avoid misleading signals.

Visual, OCR-Text, and Hybrid Evidence Retrieval for Document Visual Question Answering: A Controlled Failure Analysis

This study demonstrates that while visual-based page retrieval significantly improves evidence selection and downstream answer quality in Document Visual Question Answering compared to lexical methods, substantial performance gaps persist due to answer generation limitations even when the correct page is provided, and hybrid fusion offers no additional benefit over strong visual retrievers alone.

Interpretable Digital Twin-Safe Scheduling for Deadline-Aware Task Allocation in Dynamic Fog-Edge Computing: A Comparative and Prediction-Validity Evaluation

This paper proposes and evaluates an interpretable Digital Twin-safe scheduling framework for deadline-aware task allocation in dynamic fog-edge computing, demonstrating that a lightweight analytical Digital Twin achieves competitive performance with a hand-crafted heuristic and significantly outperforms value-based deep reinforcement learning baselines while providing robust safety guarantees and predictive diagnostics.

Game-Theoretic Workload Allocation with Dynamic Computing Efficiency and Rejection-Aware Migration in Heterogeneous Data Centers

This paper proposes a bilateral game-theoretic framework for heterogeneous data centers that jointly optimizes task migration and acceptance decisions by modeling load-dependent computing efficiency and rejection penalties, thereby achieving superior system utility and energy efficiency compared to existing static or unilateral approaches.

Who Governs Autonomous AI Execution? Execution Governance AI (EGA) V9: A Deterministic Runtime Governance Framework for Trustworthy Autonomous Workflows.

Execution Governance AI (EGA) V9 is a deterministic runtime framework that enables trustworthy autonomous workflows by combining replay consistency, provenance verification, and fail-closed containment to achieve 100% detection of execution divergence with zero false positives or negatives and no additional language-model overhead, while transparently acknowledging specific limitations in post-incident restrictions and side-effect guarantees.
