Hystar: Hypernetwork-driven Style-adaptive Retrieval via Dynamic SVD Modulation

Yujia Cai, Boxuan Li, Chenghao Xu +1

Query-based image retrieval (QBIR) requires retrieving relevant images given diverse and often stylistically heterogeneous queries, such as sketches, artworks, or low-resolution pr…

Revealing and Enhancing Core Visual Regions: Harnessing Internal Attention Dynamics for Hallucination Mitigation in LVLMs

Guangtao Lyu, Qi Liu, Chenghao Xu +5

LVLMs have achieved strong multimodal reasoning capabilities but remain prone to hallucinations, producing outputs inconsistent with visual inputs or user instructions. Existing tr…

Beyond Global Alignment: Fine-Grained Motion-Language Retrieval via Pyramidal Shapley-Taylor Learning

Hanmo Chen, Guangtao Lyu, Chenghao Xu +3

As a foundational task in human-centric cross-modal intelligence, motion-language retrieval aims to bridge the semantic gap between natural language and human motion, enabling intu…

Towards Interpretable Hallucination Analysis and Mitigation in LVLMs via Contrastive Neuron Steering

Guangtao Lyu, Xinyi Cheng, Qi Liu +5

LVLMs achieve remarkable multimodal understanding and generation but remain susceptible to hallucinations. Existing mitigation methods predominantly focus on output-level adjustmen…

Towards Arbitrary Motion Completing via Hierarchical Continuous Representation

Chenghao Xu, Guangtao Lyu, Qi Liu +3

Physical motions are inherently continuous, and higher camera frame rates typically contribute to improved smoothness and temporal coherence. For the first time, we explore continu…

A Turn Toward Better Alignment: Few-Shot Generative Adaptation with Equivariant Feature Rotation

Chenghao Xu, Qi Liu, Jiexi Yan +2

Few-shot image generation aims to effectively adapt a source generative model to a target domain using very few training images. Most existing approaches introduce consistency cons…
