Everything to the Synthetic: Diffusion-driven Test-time Adaptation via Synthetic-Domain Alignment

CVPR 2025poster

Test-time adaptation (TTA) aims to improve the performance of source-domain pre-trained models on previously unseen, shifted target domains. Traditional TTA methods primarily adapt model weights based on target data streams, making model performance sensitive to the amount and order of target data.…

OVO-Bench: How Far is Your Video-LLMs from Real-World Online Video Understanding?

CVPR 2025poster

Temporal Awareness, the ability to reason dynamically based on the timestamp when a question is raised, is the key distinction between offline and online video LLMs. Unlike offline models, which rely on complete videos for static, post hoc analysis, online models process video streams incrementally…

Demystify Mamba in Vision: A Linear Attention Perspective

NeurIPS 2024poster

Mamba is an effective state space model with linear computation complexity. It has recently shown impressive efficiency in dealing with high-resolution inputs across various vision tasks. In this paper, we reveal that the powerful Mamba model shares surprising similarities with linear attention Tran…

LLaVA-UHD: an LMM Perceiving any Aspect Ratio and High-Resolution Images

ECCV 2024poster

"Visual encoding constitutes the basis of large multimodal models (LMMs) in understanding the visual world. Conventional LMMs process images in fixed sizes and limited resolutions, while recent explorations in this direction are limited in adaptivity, efficiency, and even correctness. In this work,…

Using Human Feedback to Fine-tune Diffusion Models without Any Reward Model

CVPR 2024poster

Using reinforcement learning with human feedback (RLHF) has shown significant promise in fine-tuning diffusion models. Previous methods start by training a reward model that aligns with human preferences then leverage RL techniques to fine-tune the underlying models. However crafting an efficient re…

Causal Intervention for Human Trajectory Prediction with Cross Attention Mechanism

AAAI 2023technical

Human trajectory Prediction (HTP) in complex social environments plays a crucial and fundamental role in artificial intelligence systems. Conventional methods make use of both history behaviors and social interactions to forecast future trajectories. However, we demonstrate that the social environme…

On the Integration of Self-Attention and Convolution

CVPR 2022poster

Convolution and self-attention are two powerful techniques for representation learning, and they are usually considered as two peer approaches that are distinct from each other. In this paper, we show that there exists a strong underlying relation between them, in the sense that the bulk of computat…
