Low-Dose CT Reconstruction Using Dataset-free Learning

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Renfang Wang, Hong Qiu, , | Summary: Low-Dose computer tomography (LDCT) is an ideal alternative to reduce radiation risk in clinical applications. Although supervised-deep-learning-based reconstruction methods have demonstrated superior performance compared to conventional model-driven reconstruction algorithms, they require collecting massive pairs of low-dose and norm-dose […]

Universal Prompt Optimizer for Safe Text-to-Image Generation

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zongyu Wu, Hongcheng Gao, Yueze Wang, Xiang Zhang, Suhang Wang | Summary: Text-to-Image (T2I) models have shown great performance in generating images based on textual prompts. However, these models are vulnerable to unsafe input to generate unsafe content like sexual, harassment and illegal-activity images. Existing studies based […]

A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]
