Quick overview
Modern black-box Image-to-Video (I2V) models offer powerful automated content creation, yet lack fine-grained control and reliability due to stochastic outputs. This paper introduces an 'Agentic Self-Improvement' framework that reframes video synthesis as closed-loop, goal-directed optimization. Stage one iteratively refines prompts using a multimodal LLM with Davidsonian Scene Graph (DSG) queries for semantic adherence and Common Mistake Questions (CMQ) for artifact detection. Stage two applies Bayesian optimization to co-tune stochastic seeds and CFG scales, guided by quality metrics including a novel Video-Text Adherence (VTA) score. In human preference studies, agentic videos achieved win rates up to 69%, significantly outperforming unguided search. This work offers a practical method for enhancing predictability and control, moving video generation toward reliable production-ready tools.
- Introduces an Agentic Self-Improvement framework that frames I2V generation as closed-loop optimization, jointly refining prompts and generation parameters in two stages.
- Novel use of DSG queries and CMQ detection with a new VTA score enables automated evaluation of semantic adherence and artifacts.
- Human preference tests show win rates up to 69%, significantly outperforming unguided search methods.

FeaturedEquivariant Learning of a Transferable Three-Dimensional Classical Density Functional
等变学习可迁移的三维经典密度泛函
The most striking aspect of this paper is its direct coupling of machine learning to a core problem in statistical mechanics, using equivariant networks to learn a transferable density functional without any labels. For researchers in liquid physics or soft matter, this could be a new paradigm: do we need to run separate simulations for every new system anymore? For AI researchers, it also shows how to embed physical symmetries and variational principles into models rather than just fitting data. I recommend focusing on the methods, especially how equivariance and variational consistency are implemented—that's the real essence.
