Beyond On-Policy Exploration: Integrating External Policy Rollouts for Reinforcement Learning in Diffusion Language Models

Wonseok Lee, Jimyeong Kim, Jungmin Ko +1

Recent reinforcement learning methods for diffusion large language models (dLLMs) commonly rely on on-policy rollouts generated by the target dLLM itself. When successful on-policy…

Orthogonal Negative Guidance in Attention Feature Space for Text-to-Image Generation

Jungmin Ko, Jungwon Park, Jimyeong Kim +3

Text-to-image (T2I) models have become increasingly capable of generating high-quality images. Yet, enforcing the explicit absence of a specified object or attribute remains a fund…

Progressive Multimodal Search and Reasoning for Knowledge-Intensive Visual Question Answering

Changin Choi, Wonseok Lee, Jungmin Ko +1

Knowledge-intensive visual question answering (VQA) requires external knowledge beyond image content, demanding precise visual grounding and coherent integration of visual and text…

Task-Specific Preconditioner for Cross-Domain Few-Shot Learning

Suhyun Kang, Jungwon Park, Wonseok Lee +1

Cross-Domain Few-Shot Learning~(CDFSL) methods typically parameterize models with task-agnostic and task-specific parameters. To adapt task-specific parameters, recent approaches h…
