Bridging the Semantic-Utility Gap in Multimodal RAG via Generator-in-the-Loop Alignment

Zhan-Lun Chang, Dong-Jun Han, Seyyedali Hosseinalipour +2

Vision-language models (VLMs) augmented with retrieval-augmented generation (RAG) benefit from access to external evidence. However, standard retrievers and rerankers optimize for…

Learning to See What You Need: Gaze Attention for Multimodal Large Language Models

Junha Song, Byeongho Heo, Geonmo Gu +3

When humans describe a visual scene, they do not process the entire image uniformly; instead, they selectively fixate on regions relevant to their intended description. In contrast…

Disentangled Sparse Representations for Concept-Separated Diffusion Unlearning

Hyeonjin Kim, Hangyeol Jung, Heechan Yun +2

Unlearning specific concepts in text-to-image diffusion models has become increasingly important for preventing undesirable content generation. Among prior approaches, sparse autoe…

Iterative Critique-and-Routing Controller for Multi-Agent Systems with Heterogeneous LLMs

Wenzhi Fang, Liangqi Yuan, Guangchen Lan +2

Multi-agent large language model (LLM) systems often rely on a controller to coordinate a pool of heterogeneous models, yet existing controllers are typically limited to one-shot r…

Self-Play Enhancement via Advantage-Weighted Refinement in Online Federated LLM Fine-Tuning with Real-Time Feedback

Seohyun Lee, Wenzhi Fang, Dong-Jun Han +2

Recent works have advanced feedback-based learning systems, whereby a foundation model is able to intake incoming feedback (e.g., a user) to self-improve, creating a self-loop syst…

Sporadic Gradient Tracking over Directed Graphs: A Theoretical Perspective on Decentralized Federated Learning

Shahryar Zehtabi, Dong-Jun Han, Seyyedali Hosseinalipour +1

Decentralized Federated Learning (DFL) enables clients with local data to collaborate in a peer-to-peer manner to train a generalized model. In this paper, we unify two branches of…
