The Department of Energy’s Artificial Intelligence and Technology Office
along with The National Nuclear Security Agency’s Office of Proliferation (NNSA) presents its 2023 Challenge:

Finding Indicators of Nuclear Activity in Open-Source Images using AI/ML
Today, limited quantities of real images relevant to some types of nuclear activities exist in open sources – too few to train robust computer vision models for the wide variance required in the operational environment. In anticipation of extremely limited data environments, computer vision models must be able to train exclusively on synthetic, computer-generated images, while achieving high performance on real-world images.
