Investigating The Functional Roles of Attention Heads in Vision Language Models: Evidence for Reasoning Modules

Yanbei Jiang, Xueqi Ma, Shu Liu +5

Despite excelling on multimodal benchmarks, vision-language models (VLMs) largely remain a black box. In this paper, we propose a novel interpretability framework to systematically…

PROPA: Toward Process-level Optimization in Visual Reasoning via Reinforcement Learning

Yanbei Jiang, Chao Lei, Yihao Ding +2

Despite significant progress, Vision-Language Models (VLMs) still struggle with complex visual reasoning, where multi-step dependencies cause early errors to cascade through the re…

Adaptive Segmentation of EEG for Machine Learning Applications

Johnson Zhou, Joseph West, Krista A. Ehinger +3

Objective. Electroencephalography (EEG) data is derived by sampling continuous neurological time series signals. In order to prepare EEG signals for machine learning, the signal mu…

Beyond Perception: Evaluating Abstract Visual Reasoning through Multi-Stage Task

Yanbei Jiang, Yihao Ding, Chao Lei +3

Current Multimodal Large Language Models (MLLMs) excel in general visual reasoning but remain underexplored in Abstract Visual Reasoning (AVR), which demands higher-order reasoning…

Open-World Amodal Appearance Completion

Jiayang Ao, Yanbei Jiang, Qiuhong Ke +1

Understanding and reconstructing occluded objects is a challenging problem, especially in open-world scenarios where categories and contexts are diverse and unpredictable. Traditio…

KALE: An Artwork Image Captioning System Augmented with Heterogeneous Graph

Yanbei Jiang, Krista A. Ehinger, Jey Han Lau

Exploring the narratives conveyed by fine-art paintings is a challenge in image captioning, where the goal is to generate descriptions that not only precisely represent the visual…

Sequential Amodal Segmentation via Cumulative Occlusion Learning

Jiayang Ao, Qiuhong Ke, Krista A. Ehinger

To fully understand the 3D context of a single image, a visual system must be able to segment both the visible and occluded regions of objects, while discerning their occlusion ord…
