MobileViTv2 with a normalised cosine-similarity classification head and synthetic data balancing for ECG arrhythmia classification on the MIT-BIH Arrhythmia Database

This paper presents a MobileViTv2-based hybrid network enhanced with a normalised cosine-similarity classification head and WGAN-GP synthetic data balancing, which achieves high intra-patient accuracy on the MIT-BIH Arrhythmia Database while highlighting the necessity for future patient-independent validation.

Autoencoder–Graph Neural Network Framework for Robust 3D Pore Connectivity Classification in Noisy Volumetric Images

This study demonstrates that Graph Neural Networks, particularly GraphSAGE enhanced with geometric features, significantly outperform traditional thresholding methods in classifying 3D pore connectivity within noisy volumetric images, although improved edge classification does not always guarantee better overall cluster or percolation predictions.

Familiarity, Not Detection: Rethinking Machine-Learning Hardware Trojan Detection Under Leakage-Free Side-Channel Evaluation

This paper demonstrates that the high accuracy of machine-learning hardware Trojan detectors on standard benchmarks is an artifact of data leakage caused by random trace-level splits, revealing that true cross-Trojan detection performance collapses to chance levels and necessitates per-chip calibration rather than universal pretrained models.

Auditing the Auditor: Extraction Accuracy, Hallucination, and Abstention in Open-Weight LLMs for ESG Reporting A Longitudinal Empirical Benchmark Across 518 Corporate Disclosures (2010–2026)

This longitudinal benchmark of five open-weight LLMs across 518 ESG reports reveals that while models reliably summarize narrative policies, they struggle with precise numerical extraction and frequently hallucinate data without explicit reasoning or strict instructions, highlighting a critical need for improved abstention mechanisms in automated sustainability auditing.

Function Recognition from Raw Power Side Channels in Bare-Metal Embedded Systems: Feasibility and Limits

This paper demonstrates that while recognizing specific C functions from raw power traces in bare-metal embedded systems is feasible using class-specific autoencoders, the approach faces inherent physical limits due to signal similarities and variations, positioning it as a complementary behavioral signal rather than a standalone security detector.

When Sources Disagree: Accuracy-Preserving Batch Verification and the Limits of Source-Age Screening in Retrieval-Augmented Generation

This paper demonstrates that while length-sorted batch inference can improve processing throughput without sacrificing accuracy in retrieval-augmented generation verification, a simple source-age screening rule is insufficient for detecting factual obsolescence and should be replaced by content-aware temporal checks.
