Fixing Abstention with Token Probability: A Budget-Matched Causal Test Across Four Small Open-Weight Models

This paper demonstrates that replacing verbalized confidence with a budget-matched token-probability abstention policy causally eliminates a specific accuracy-degrading effect observed in the llama3.2:1b model, but fails to generalize this benefit to other small open-weight models, indicating that such fixes are model-specific and that fixed-budget abstention can remain net-harmful even with improved targeting.

Explainable Digital Twin Modelling of Semi-Urban Community for Multidimensional Poverty Governance Intelligence

This study proposes an explainable Digital Twin framework that integrates machine learning, counterfactual simulation, and cost-aware optimization to model multidimensional poverty dynamics in Nigeria's semi-urban Isolu community, demonstrating that targeted, cluster-specific multi-policy interventions are more effective than uniform safety nets for intelligent poverty governance.

From Pixels to Registers: A Multi-Modal Testing Framework for Chained Perception, Control and Firmware

This paper presents a multi-modal testing framework that decouples perception from control by converting photorealistic inputs into abstract line drawings and semantic maps, validated through a novel open simulator that bridges fast training-level fidelity with rigorous register-level firmware emulation to expose defects invisible to standard simulation.

Design and Evaluation of Reinforcement-Learning Scheduling for Multi-Stage OSAT Manufacturing: A Verified Scoping Review, Executable Benchmark, and Decision Framework for Viet Nam

This study addresses the gap in applying reinforcement learning to OSAT manufacturing by developing an executable benchmark and decision framework that reveals adaptive scheduling policies offer selective, objective-specific advantages over traditional heuristics rather than a universal replacement, thereby guiding managers on the trade-offs and requirements for operational deployment in Vietnam.

Transformation-Specific Robustness Evaluation of a Machine Learning-Based Network Intrusion Detection System Under Controlled Feature Perturbations

This study evaluates the transformation-specific robustness of machine learning-based network intrusion detection systems on the UNSW-NB15 dataset, revealing that while models exhibit varying sensitivity to feature perturbations, a TTL-aware training configuration significantly reduces performance degradation under negative time-to-live modifications compared to a standard baseline.
