AgentGrad: Intervention-guided Prompt Optimization for Multi Agent Systems

Jaewon Chu, Jinwoo Seo, Jaewon Cho +4

Large language model (LLM)-based multi-agent systems (MAS) achieve strong performance by employing specialized multiple agents, yet their performance depends on the prompt design o…

PatchGate: Narrowing the Verbalization Gap with Intrinsic Object Inventories in Frozen Vision-Language Models

Jihyung Ko, Eunji Jung, Hyeongsub Kim +4

Reliable image captioning in Vision-Language Models (VLMs) requires captions to be both precise and complete, avoiding unsupported object mentions while covering visible objects. E…

Context Blindness in DPO: Mitigating Object Hallucination in MLLMs via Context-Calibrated Preference Optimization

Byungoh Ko, Jinyoung Park, Jongha Kim +3

Multimodal large language models (MLLMs) have made rapid progress, yet they still exhibit object hallucination, generating plausible but incorrect descriptions that are inconsisten…

MoLT: Mixture of Layer-Wise Tokens for Efficient Audio-Visual Learning

Kyeongha Rho, Hyeongkeun Lee, Jae Won Cho +1

In this paper, we propose Mixture of Layer-Wise Tokens (MoLT), a parameter- and memory-efficient adaptation framework for audio-visual learning. The key idea of MoLT is to replace…

Let Me Finish My Sentence: Video Temporal Grounding with Holistic Text Understanding

Jongbhin Woo, Hyeonggon Ryu, Youngjoon Jang +2

Video Temporal Grounding (VTG) aims to identify visual frames in a video clip that match text queries. Recent studies in VTG employ cross-attention to correlate visual frames and t…

Preserving Multi-Modal Capabilities of Pre-trained VLMs for Improving Vision-Linguistic Compositionality

Youngtaek Oh, Jae Won Cho, Dong-Jin Kim +2

In this paper, we propose a new method to enhance compositional understanding in pre-trained vision and language models (VLMs) without sacrificing performance in zero-shot multi-mo…
