DeCafNet: Delegate and Conquer for Efficient Temporal Grounding in Long Videos

CVPR 2025poster

Long Video Temporal Grounding (LVTG) aims at identifying specific moments within lengthy videos based on user-provided text queries for effective content retrieval. The approach taken by existing methods of dividing video into clips and processing each clip via a full-scale expert encoder is challen…

Hummingbird: High Fidelity Image Generation via Multimodal Context Alignment

ICLR 2025poster

While diffusion models are powerful in generating high-quality, diverse synthetic data for object-centric tasks, existing methods struggle with scene-aware tasks such as Visual Question Answering (VQA) and Human-Object Interaction (HOI) Reasoning, where it is critical to preserve scene attributes in…

Jailbreak Distillation: Renewable Safety Benchmarking

EMNLP 2025

Large language models (LLMs) are rapidly deployed in critical applications, raising urgent needs for robust safety benchmarking. We propose Jailbreak Distillation (JBDistill), a novel benchmark construction framework that “distills” jailbreak attacks into high-quality and easily-updatable safety ben

What To Look at and Where: Semantic and Spatial Refined Transformer for Detecting Human-Object Interactions

CVPR 2022oral

We propose a novel one-stage Transformer-based semantic and spatial refined transformer (SSRT) to solve the Human-Object Interaction detection task, which requires to localize humans and objects, and predicts their interactions. Differently from previous Transformer-based HOI approaches, which mostl…

VSGNet: Spatial Attention Network for Detecting Human Object Interactions Using Graph Convolutions

CVPR 2020poster

Comprehensive visual understanding requires detection frameworks that can effectively learn and utilize object interactions while analyzing objects individually. This is the main objective in Human-Object Interaction (HOI) detection task. In particular, relative spatial reasoning and structural conn…
