PromptDyG: Test-Time Prompt Adaptation on Dynamic Graphs
Guoguo Ai, Chaoxi Niu, Hui Yan +3
Activities in numerous evolving systems can be represented as dynamic graphs in snapshot form at different time intervals, i.e., discrete-time dynamic graphs (DTDGs). Existing meth…
Agentic Spatio-Temporal Grounding via Collaborative Reasoning
Heng Zhao, Yew-Soon Ong, Joey Tianyi Zhou
Spatio-Temporal Video Grounding (STVG) aims to retrieve the spatio-temporal tube of a target object or person in a video given a text query. Most existing approaches perform frame-…
DP-CSGP: Differentially Private Stochastic Gradient Push with Compressed Communication
Zehan Zhu, Heng Zhao, Yan Huang +3
In this paper, we propose a Differentially Private Stochastic Gradient Push with Compressed communication (termed DP-CSGP) for decentralized learning over directed graphs. Differen…
Cognitive Inception: Agentic Reasoning against Visual Deceptions by Injecting Skepticism
Yinjie Zhao, Heng Zhao, Bihan Wen +1
As the development of AI-generated contents (AIGC), multi-modal Large Language Models (LLM) struggle to identify generated visual inputs from real ones. Such shortcoming causes vul…
Dynamic-Aware Video Distillation: Optimizing Temporal Resolution Based on Video Semantics
Yinjie Zhao, Heng Zhao, Bihan Wen +2
With the rapid development of vision tasks and the scaling on datasets and models, redundancy reduction in vision datasets has become a key area of research. To address this issue,…
Video Set Distillation: Information Diversification and Temporal Densification
Yinjie Zhao, Heng Zhao, Bihan Wen +2
The rapid development of AI models has led to a growing emphasis on enhancing their capabilities for complex input data such as videos. While large-scale video datasets have been i…
