Self-Distilled Reasoner: On-Policy Self-Distillation for Large Language Models

This paper introduces On-Policy Self-Distillation (OPSD), a framework where a single large language model acts as both teacher and student by leveraging privileged reasoning traces to supervise its own weaker policy, thereby achieving superior mathematical reasoning performance and significantly higher token efficiency compared to traditional off-policy distillation and reinforcement learning methods.

Mobility-Embedded POIs: Learning What A Place Is and How It Is Used from Human Movement

This paper introduces Mobility-Embedded POIs (ME-POIs), a framework that enhances general-purpose point-of-interest representations by integrating large-scale human mobility data with language model embeddings to capture both place identity and real-world usage functions, thereby outperforming existing text-only and mobility-only baselines across diverse map enrichment tasks.

Supervised Metric Regularization Through Alternating Optimization for Multi-Regime Physics-Informed Neural Networks

This paper introduces Topology-Aware PINNs (TAPINN), a novel framework that employs supervised metric regularization and alternating optimization to effectively resolve spectral bias and mode collapse in multi-regime physics-informed neural networks, achieving superior convergence stability and accuracy compared to standard and hypernetwork-based baselines.

Empirical Stability Analysis of Kolmogorov-Arnold Networks in Hard-Constrained Recurrent Physics-Informed Discovery

This paper empirically demonstrates that while Kolmogorov-Arnold Networks (KANs) can compete with MLPs on simple univariate residuals in hard-constrained recurrent physics-informed architectures, they suffer from severe hyperparameter fragility, instability in deeper configurations, and consistent failure on multiplicative terms, ultimately revealing limitations in their additive inductive bias for modeling state coupling in oscillatory systems.
