Beyond Static Allocation: Dynamic Sensitivity-Aware Fine-Tuning for Vision Transformers

ICML 2026poster

Existing Parameter-Efficient Fine-Tuning (PEFT) methods are fundamentally constrained by a static allocation paradigm, which overlooks the model's evolving optimization priorities during training. To address this, we introduce Dynamic Adaptive Fine-tuning (DAF), a novel framework that periodically e…

Bridging Pixels and Words: Mask-Aware Local Semantic Fusion for Multimodal Media Verification

CVPR 2026

As the harm caused by fake news grows, the task of detecting and grounding multi-modal media manipulation (DGM4) is gaining more attention. Existing multimodal methods overlook fine-grained semantic alignment between visual and textual modalities, thereby limiting their ability to detect sophisticat

I2-World: Intra-Inter Tokenization for Efficient Dynamic 4D Scene Forecasting

ICCV 2025poster

Forecasting the evolution of 3D scenes and generating unseen scenarios through occupancy-based world models offers substantial potential to enhance the safety of autonomous driving systems. While tokenization has revolutionized image and video generation, efficiently tokenizing complex 3D scenes rem…

STCOcc: Sparse Spatial-Temporal Cascade Renovation for 3D Occupancy and Scene Flow Prediction

CVPR 2025poster

3D occupancy and scene flow offer a detailed and dynamic representation of 3D scene. Recognizing the sparsity and complexity of 3D space, previous vision-centric methods have employed implicit learning-based approaches to model spatial and temporal information. However, these approaches struggle to…

Stochastic-Aware Mamba Diffusion for Pedestrian Trajectory Prediction

ICASSP 2025accepted

Pedestrian trajectory prediction plays a crucial role in understanding human behavior and intentions. Due to the inherent randomness in human movement, current research constructs trajectories in stochastic space and uses diffusion models to reverse the denoising process. The commonly used denoising…

TOTP: Transferable Online Pedestrian Trajectory Prediction with Temporal-Adaptive Mamba Latent Diffusion

ICCV 2025poster

Pedestrian trajectory prediction is crucial for many intelligent tasks. While existing methods predict future trajectories from fixed-frame historical observations, they are limited by the observational perspective and the need for extensive historical information, resulting in prediction delays and…

Task-Driven Exploration: Decoupling and Inter-Task Feedback for Joint Moment Retrieval and Highlight Detection

CVPR 2024poster

Video moment retrieval and highlight detection are two highly valuable tasks in video understanding but until recently they have been jointly studied. Although existing studies have made impressive advancement recently they predominantly follow the data-driven bottom-up paradigm. Such paradigm overl…
