UI2Code^N: UI-to-Code Generation as Interactive Visual Optimization

ICML 2026poster

UI-to-code aims to translate UI screenshots into executable front-end code. Despite progress with vision-language models (VLMs), most existing methods formulate UI-to-code as a single-pass generation, which mismatches real-world UI development that is inherently iterative and feedback-driven. We ref…

A Survey of Post-Training Scaling in Large Language Models

ACL 2025long

Large language models (LLMs) have achieved remarkable proficiency in understanding and generating human natural languages, mainly owing to the “scaling law” that optimizes relationships among language modeling loss, model parameters, and pre-trained tokens. However, with the exhaustion of high-quali…

SPaR: Self-Play with Tree-Search Refinement to Improve Instruction-Following in Large Language Models

ICLR 2025poster

Instruction-following is a fundamental capability of language models, requiring the model to recognize even the most subtle requirements in the instructions and accurately reflect them in its output. Such an ability is well-suited for and often optimized by preference learning. However, existing met…

VPO: Aligning Text-to-Video Generation Models with Prompt Optimization

ICCV 2025poster

Video generation models have achieved remarkable progress in text-to-video tasks. These models are typically trained on text-video pairs with highly detailed and carefully crafted descriptions, while real-world user inputs during inference are often concise, vague, or poorly structured. This gap mak…

Black-Box Prompt Optimization: Aligning Large Language Models without Model Training

ACL 2024long

Large language models (LLMs) have shown impressive success in various applications. However, these models are often not well aligned with human intents, which calls for additional treatments on them; that is, the alignment problem. To make LLMs better follow user instructions, existing alignment met…

CritiqueLLM: Towards an Informative Critique Generation Model for Evaluation of Large Language Model Generation

ACL 2024long

Since the natural language processing (NLP) community started to make large language models (LLMs) act as a critic to evaluate the quality of generated texts, most of the existing works train a critique generation model on the evaluation data labeled by GPT-4’s direct prompting. We observe that thes…
