APEX: Assumption-free Projection-based Embedding eXamination Metric for Image Quality Assessment

Researchers introduce APEX, a novel image quality assessment metric that addresses fundamental limitations in existing evaluation methods like FID by using Sliced Wasserstein Distance and modern foundation models (CLIP, DINOv2) as embedding-agnostic feature extractors. The framework eliminates parametric assumptions while maintaining scalability to high-dimensional spaces, demonstrating superior robustness and stability across datasets.

Generalization Properties of Score-matching Diffusion Models for Intrinsically Low-dimensional Data

Researchers developed new theoretical guarantees for score-based diffusion models that better reflect real-world data structures. The analysis shows these models can adapt to intrinsic low-dimensional geometry and avoid the curse of dimensionality through convergence rates based on Wasserstein dimension rather than ambient dimension.

Robust $Q$-learning for mean-field control under Wasserstein uncertainty in common noise

Researchers have developed a robust Q-learning algorithm for mean-field control problems that handles uncertainty in common noise using Wasserstein distance methods. The algorithm combines quantization-projection schemes with dual reformulation and demonstrates convergence guarantees with finite-time bounds, validated through systemic risk and epidemic modeling simulations.
