A Risk-Oriented Verification and Validation Framework for Hallucination Detection in Public-Sector LLM Systems

This paper proposes a risk-oriented verification and validation framework that transforms hallucination detection in public-sector LLMs from a purely technical challenge into a governance issue by introducing a composite risk index to guide operational decisions like deferral or human escalation, thereby ensuring legal certainty and administrative accountability.

Deep Learning for Student Outcomes Temporal Deep Learning for Student Outcome Prediction: Comparing Multi-Task and Single-Task Approaches on the OULAD Dataset

Using the OULAD dataset, this study demonstrates that while BiLSTM models outperform gradient boosting baselines in predicting student pass/fail and withdrawal outcomes, multi-task learning architectures provide no significant advantage over single-task approaches despite moderate task correlation, suggesting that these outcomes rely on partially distinct behavioral patterns.

QKT: Quantum Kernel Transformer for High-Dimensional Classification Across Modalities

The paper introduces the Quantum Kernel Transformer (QKT), a hybrid architecture that leverages a trainable parameterized quantum circuit as a non-linear embedding layer to achieve competitive or superior performance on diverse high-dimensional classification tasks across text, tabular, audio, and physics domains, while demonstrating robustness against instability and identifying specific limitations in image processing.
