    The method couples a high-fidelity, asymptotic-preserving VPL solver with inexpensive, strongly correlated surrogates based on the Vlasov--Poisson--Fokker--Planck (VPFP) and Euler--Poisson (EP) equations.

    Analysis

    This paper introduces Bayesian Self-Distillation (BSD), a novel approach to training deep neural networks for image classification. It addresses the limitations of traditional supervised learning and existing self-distillation methods by using Bayesian inference to create sample-specific target distributions. The key advantage is that BSD avoids reliance on hard targets after initialization, leading to improved accuracy, calibration, robustness, and performance under label noise. The results demonstrate significant improvements over existing methods across various architectures and datasets.
    Reference

    BSD consistently yields higher test accuracy (e.g. +1.4% for ResNet-50 on CIFAR-100) and significantly lower Expected Calibration Error (ECE) (-40% ResNet-50, CIFAR-100) than existing architecture-preserving self-distillation methods.

    Analysis

    This paper presents a training-free, graph-based approach to solve interactive reasoning tasks in the ARC-AGI-3 benchmark, a challenging environment for AI agents. The method's success in outperforming LLM-based agents highlights the importance of structured exploration, state tracking, and action prioritization in environments with sparse feedback. This work provides a strong baseline and valuable insights into tackling complex reasoning problems.
