CASC’s Machine Intelligence Group was founded in 2020 to create a home base for technical staff and postdocs conducting fundamental and applied research in machine learning (ML) in support of the Laboratory’s national security missions. Our research portfolio includes a broad set of topics stemming from the growing field of scientific ML, including representation learning, adversarial methods, uncertainty quantification, graph learning, generalizability, interpretability, and model calibration.
