DeepFake-Adapter: Dual-Level Adapter for DeepFake Detection

1 code implementation1 Jun 2023 Rui Shao, Tianxing Wu, Liqiang Nie, Ziwei Liu

Unlike existing deepfake detection methods merely focusing on low-level forgery patterns, the forgery detection process of our model can be regularized by generalizable high-level semantics from a pre-trained ViT and adapted by global and local low-level forgeries of deepfake data.

Semantic Guided and Response Times Bounded Top-k Similarity Search over Knowledge Graphs

2 code implementations15 Oct 2019 Yu-Xiang Wang, Arijit Khan, Tianxing Wu, Jiahui Jin, Haijiang Yan

We face two challenges on graph query over a knowledge graph: (1) the structural gap between $G_Q$ and the predefined schema in $G$ causes mismatch with query graph, (2) users cannot view the answers until the graph query terminates, leading to a longer system response time (SRT).
