UFID: A Unified Framework for Input-level Backdoor Detection on Diffusion Models

no code implementations1 Apr 2024 Zihan Guan, Mengxuan Hu, Sheng Li, Anil Vullikanti

Diffusion Models are vulnerable to backdoor attacks, where malicious attackers inject backdoors by poisoning some parts of the training samples during the training stage.

Img2Loc: Revisiting Image Geolocalization using Multi-modality Foundation Models and Image-based Retrieval-Augmented Generation

no code implementations28 Mar 2024 Zhongliang Zhou, Jielu Zhang, Zihan Guan, Mengxuan Hu, Ni Lao, Lan Mu, Sheng Li, Gengchen Mai

Geolocating precise locations from images presents a challenging problem in computer vision and information retrieval. Traditional methods typically employ either classification, which dividing the Earth surface into grid cells and classifying images accordingly, or retrieval, which identifying locations by matching images with a database of image-location pairs.

Bridging Causal Discovery and Large Language Models: A Comprehensive Survey of Integrative Approaches and Future Directions

no code implementations16 Feb 2024 Guangya Wan, Yuqi Wu, Mengxuan Hu, Zhixuan Chu, Sheng Li

Causal discovery (CD) and Large Language Models (LLMs) represent two emerging fields of study with significant implications for artificial intelligence.

Causal Discovery

Task-Driven Causal Feature Distillation: Towards Trustworthy Risk Prediction

no code implementations20 Dec 2023 Zhixuan Chu, Mengxuan Hu, Qing Cui, Longfei Li, Sheng Li

To address this, we propose a Task-Driven Causal Feature Distillation model (TDCFD) to transform original feature values into causal feature attributions for the specific risk prediction task.

XAI meets Biology: A Comprehensive Review of Explainable AI in Bioinformatics Applications

no code implementations11 Dec 2023 Zhongliang Zhou, Mengxuan Hu, Mariah Salcedo, Nathan Gravel, Wayland Yeung, Aarya Venkat, Dongliang Guo, Jielu Zhang, Natarajan Kannan, Sheng Li
