GUIDE: Guiding Internal Evidence with Language Instructions

Soyeon Caren Han, Hyunsuk Chung, Jinwoo Kim +2

Large multimodal models follow instructions about what to generate, but not necessarily about what evidence to rely on. Hence, models may continue to depend on shortcut-associated…

Physics-based phenomenological characterization of cross-modal bias in multimodal models

Hyeongmo Kim, Sohyun Kang, Yerin Choi +5

The term 'algorithmic fairness' is used to evaluate whether AI models operate fairly in both comparative (where fairness is understood as formal equality, such as "treat like cases…

FiLoRA: Focus-and-Ignore LoRA for Controllable Feature Reliance

Hyunsuk Chung, Soyeon Caren Han, Seungyeon Ji +3

Multimodal foundation models integrate heterogeneous signals across modalities, yet it remains unclear whether their predictions can be controlled by explicitly modulating reliance…

SynJAC: Synthetic-data-driven Joint-granular Adaptation and Calibration for Domain Specific Scanned Document Key Information Extraction

Yihao Ding, Soyeon Caren Han, Zechuan Li +1

Visually Rich Documents (VRDs), comprising elements such as charts, tables, and paragraphs, convey complex information across diverse domains. However, extracting key information f…

Form-NLU: Dataset for the Form Natural Language Understanding

Yihao Ding, Siqu Long, Jiabin Huang +4

Compared to general document analysis tasks, form document structure understanding and retrieval are challenging. Form documents are typically made by two types of authors; A form…

PiggyBack: Pretrained Visual Question Answering Environment for Backing up Non-deep Learning Professionals

Zhihao Zhang, Siwen Luo, Junyi Chen +4

We propose a PiggyBack, a Visual Question Answering platform that allows users to apply the state-of-the-art visual-language pretrained models easily. The PiggyBack supports the fu…

V-Doc : Visual questions answers with Documents

Yihao Ding, Zhe Huang, Runlin Wang +5

We propose V-Doc, a question-answering tool using document images and PDF, mainly for researchers and general non-deep learning experts looking to generate, process, and understand…
