BACAM: Behavior-Aware Continual Agent Merging for Multi-Turn Interaction

Shuaitong Li, Baochen Xiong, Xiaoshan Yang +4

Model merging offers a way to integrate the capabilities of specialized experts, but existing agent merging methods typically require all of them to be available at once. We study…

UniFed-VLM: Federated Instruction Tuning for Vision-Language Models with Multiple Heterogeneity

Pengyu Wang, Baochen Xiong, Xiaoshan Yang +4

Vision-Language Models (VLMs) have demonstrated strong performance in multimodal understanding and generation. However, fine-tuning of VLMs typically relies on centralized data, wh…

Decoupled Vision-Language System for Multimodal Understanding and Generation

Yifan Xu, Baochen Xiong, Xiaoshan Yang +3

We introduce a new architecture design for multimodal large language models (MLLMs), Libra, capable of both multimodal understanding and generation. Libra architecture contains one…

VTM-Nav: Harnessing Cross-Episode Experience for Object-Goal Navigation with Hierarchical Visual-Topological Memory

Xiaoran Xu, Yupeng Wu, Tianyu Xue +4

Training-free ObjectNav agents increasingly use vision-language models (VLMs), yet typically discard acquired scene knowledge after each request. We study cross-episode ObjectNav,…

DOME: Learning Transferable Domain Variables from Sparse Supervision for Test-Time Adaptation

Xiaoran Xu, Yifan Xu, Yupeng Wu +2

Test-time adaptation (TTA) aims to align a model to shifting test domains using only unlabeled streaming data. Most existing methods implicitly infer a single global domain distrib…

A Step Toward Federated Pretraining of Multimodal Large Language Models

Baochen Xiong, Yifan Xu, Xiaoshan Yang +3

The rapid evolution of Multimodal Large Language Models (MLLMs) is bottlenecked by the saturation of high-quality public data, while vast amounts of diverse multimodal data remain…

Towards Domain-Generalized Open-Vocabulary Object Detection: A Progressive Domain-invariant Cross-modal Alignment Method

Xiaoran Xu, Xiaoshan Yang, Jiangang Yang +3

Open-Vocabulary Object Detection (OVOD) has achieved remarkable success in generalizing to novel categories. However, this success often rests on the implicit assumption of domain…

Libra: Building Decoupled Vision System on Large Language Models

Yifan Xu, Xiaoshan Yang, Yaguang Song +1

In this work, we introduce Libra, a prototype model with a decoupled vision system on a large language model (LLM). The decoupled vision system decouples inner-modal modeling and c…

Exploring Multi-Modal Contextual Knowledge for Open-Vocabulary Object Detection

Yifan Xu, Mengdan Zhang, Xiaoshan Yang +1

In this paper, we for the first time explore helpful multi-modal contextual knowledge to understand novel categories for open-vocabulary object detection (OVD). The multi-modal con…

Towards Corruption-Agnostic Robust Domain Adaptation

Yifan Xu, Kekai Sheng, Weiming Dong +3

Big progress has been achieved in domain adaptation in decades. Existing works are always based on an ideal assumption that testing target domain are i.i.d. with training target do…
