Mining AI-Assisted Course Design Workflows at Production Scale

This paper presents the first production-scale study of AI-assisted course design by mining a privacy-preserving dataset from CourseFactory to extract four workflow surfaces, demonstrating that structural-quality triage and item-to-assignment routing models significantly improve review efficiency and accuracy while confirming that withheld prompt text adds no measurable signal.

Recovery Dynamics and Persistent Structural Excursion in Disrupted World Models

This study demonstrates that while successful and failed trajectories in a disrupted world model exhibit distinct recovery dynamics—such as lower path entropy and fewer structural excursions—these full-trajectory patterns cannot be reliably predicted from early prefixes, thereby distinguishing the challenges of regime detection, recovery monitoring, and individual rollout prediction.

H. Dilpriya's Momentum (HDM) : A Multi-Strategy Gradient-Aligned Optimizer with Adaptive Per-Parameter Corrections, Cosine-Annealed Scheduling, and Convergence Guarantees for Deep Neural Networks

This paper introduces H. Dilpriya's Momentum (HDM), a novel multi-strategy optimizer that combines adaptive per-parameter corrections with cosine-annealed scheduling to achieve rigorous convergence guarantees and state-of-the-art gradient alignment, demonstrating superior performance on both ill-conditioned synthetic problems and deep learning benchmarks like MNIST and CIFAR-10.

Understanding Behavioural Risk Signals in Socio-Technical Work Systems Using Explainable Machine Learning

This study demonstrates that using explainable machine learning to analyze item-level safety climate data reveals nonlinear, threshold-dependent behavioural risk patterns driven by management responsiveness, training, and experience, challenging traditional linear aggregation models and offering a more precise basis for proactive accident prevention.

ℓ0-Regularized Quadratic Surface Support Vector Machines

This paper proposes a sparse ℓ0-regularized quadratic surface support vector machine (QSVM) to address overfitting and interpretability issues in kernel-free nonlinear classification, introducing a penalty decomposition algorithm with provable optimality and convergence guarantees that demonstrates competitive performance and sparsity on both benchmark and real-world credit datasets.

Empty scaffold allocation bias in molecular distribution shift evaluation

This paper reveals that standard scaffold-based evaluation methods introduce a hidden allocation bias by incorrectly treating chemically heterogeneous "no-scaffold" molecules as a single unit, which distorts generalization metrics across common benchmarks, and proposes an "Empty-Scaffold-Aware" repair to restore balanced representation and accurate performance assessment.
