DOHF: Online Diffusion Fine-tuning with Doob's $h$-transform Guidance

This work proposes Diffusion Online-guidance Fine-tuning (DOHF), which turns Doob's $h-transform into a practical online training algorithm and demonstrates how adapting probabilistic conditioning through inexpensive estimation and iterative distillation can improve generative learning across statistical sampling and v...

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.
