Weak-topological neural operators for certificate-guided physical prediction

This paper introduces Weak-Topological Neural Operators (WTNO), a framework that enhances neural operator selection for partial differential equations by coupling state predictors with geometric, topological, and weak-measure certificates to ensure robust physical predictions in scenarios involving interfaces, topological changes, and rare events.

Dual-Guidance Framework for Semi-Supervised Semantic Segmentation via Uncertainty and Prototypes

This paper proposes a Dual-Guidance framework for semi-supervised semantic segmentation that combines an Uncertainty-Aware Dynamic Pseudo-Label Refinement module and a Class-Prototype Contrastive Guidance module to jointly refine predictions and regularize feature representations, achieving state-of-the-art performance on PASCAL VOC 2012 and Cityscapes benchmarks.

Trustworthy AI for Marketing Measurement: A Systematic Review of Attribution, Media Mix Modeling, and Privacy-Preserving Methods

This systematic review of 108 studies (2010–2026) analyzes how AI reshapes marketing measurement by proposing a "Measure–Validate–Protect" framework that balances the enhanced predictive power of deep learning and neural media mix models against the causal limitations and accuracy costs imposed by privacy-preserving techniques.

Automated Fracture Image Captioning Using Multimodal Vision-Language Models: A Comprehensive Comparative Study on a Clinically Curated Dataset

This paper presents a comprehensive benchmark of nine encoder-decoder architectures for automated fracture radiograph captioning on a clinically curated dataset, demonstrating that the vision-language pre-trained BLIP-Base model outperforms other combinations of visual encoders and GPT-2 decoders while providing critical insights into failure modes and architectural selection for low-resource medical imaging tasks.

Foresight Is Not Enough: Sentence-Level Future Signals, Self-Loop Hard Negatives, and the Calibration Gap in Small Language Models

This paper demonstrates that while the ForesightLM-v2 model successfully learns a stable sentence-level future prediction signal, this representation fails to directly control generation behavior, revealing that its apparent benefits stem primarily from semantic reranking rather than the learned future term itself and highlighting a critical gap between learned representations and calibrated behavioral outcomes in small language models.

From Telemetry to Techniques: Behavior-Centric MITRE ATT&CK Technique Classification Through Sysmon Event Correlation

This paper proposes a behavior-centric framework that reconstructs Sysmon events into GUID-correlated sequences to improve MITRE ATT&CK technique classification, demonstrating that preserving process-level context outperforms temporal grouping and that a baseline SecureBERT model achieves superior results without explicit class imbalance mitigation.
