PT-LGBM: An End-to-End Interpretable Cross-Domain Model for High-Speed Train Bearing Fault Diagnosis Under Class Imbalance

This paper proposes PT-LGBM, an end-to-end interpretable cross-domain model that integrates geometry-partition sampling, feature alignment, and an optimized LightGBM classifier to achieve high-accuracy, reliable fault diagnosis for high-speed train bearings under conditions of class imbalance and domain shift.

How Annotator Agreement Affects Sentiment Classification Performance for Indonesian Coastal Tourism Reviews

This study demonstrates that training sentiment classifiers on a larger, majority-vote dataset of Indonesian coastal tourism reviews yields higher performance than a strictly unanimous-consensus dataset, though the results suggest that increased data volume and class balance, rather than the retention of ambiguous instances alone, may be the primary drivers of improvement while IndoBERT effectively reduces systematic misclassification of neutral reviews.

A Supervised Multimodal Benchmark and Missing-Modality Robustness Study for Robotic Welding Defect Classification

This paper introduces the first supervised four-modality benchmark and session-disjoint evaluation protocol for robotic welding defect classification, demonstrating that a modality-perturbation curriculum within the proposed MAAF-Net framework significantly enhances robustness against missing sensor data without compromising clean accuracy or inference speed.

Bilder ohne Worte: Can AI Identify Political Parties via Unspoken Visual Signatures in the 2025 German Election?

This paper introduces PREF, an interpretable vision-language model that successfully classifies political party affiliation from 2025 German election campaign media by verbalizing perceptual cues, achieving performance comparable to black-box embeddings while quantifying the extent to which party identity persists even after removing explicit branding.

Generalizing the LoD Transition Space for Continuous Multi-Scale Representation using Straight Skeletons

This paper proposes a generalized LoD Transition Space framework that utilizes straight-skeleton-based 3D volumes to enable continuous, topologically consistent multi-scale transformations between diverse geometric primitives (polygons, polylines, and points), thereby supporting smooth map generalization across arbitrary Levels of Detail.
