Black‐Box Optimization With Simultaneous Statistical Inference for Optimal Performance

This work proposes an algorithm that not only tackles the issue of sample average of performance estimates generated by the optimization algorithm, but also provides a consistent online estimator for the variance of the performance.

Leveraging Inference-Time Compute for Diffusion Models via Global Scheduling of Denoising Trajectories

The analysis from independent random search to a broader family of local search operators, and it is proved that when sensitivities vary across instances, no adaptive policy can avoid worst-case regret that grows linearly in the trajectory length.

Learning to Simulate from Heavy-Tailed Distribution via Diffusion Model

In Learning to Simulate from Heavy-Tailed Distribution via Diffusion Model, the authors pinpoint why standard diffusion models break down on heavy-tailed targets and propose a Student-t-based heavy-tailed diffusion (SHD) framework that fixes both ends of the pipeline.

Spec2Twin-Chain: Orchestrating Bi-Level Optimization with LLMs for Blockchain Digital Twin Construction

Spec2Twin-Chain is considered, a framework that formulates blockchain digital-twin construction as a bi-level optimization problem and can construct behaviorally accurate twins, improve initial designs through iterative feedback, and reuse calibrated twins to support downstream decisions.

3D-DefectBench: A Controlled Factorial Study of Vision-Language Model Evaluation Pipelines for Fine-Grained 3D Generation Defects

3D-DefectBench is introduced, a benchmark and framework for systematic analysis of VLM-based 3D defect detection pipelines, and finds that automated judges should be evaluated as complete pipelines and calibrated across human reference regimes, rather than benchmarked only as standalone models.
