An increasing number of applications are powered by machine learning (ML), often in ways not immediately evident to an end user. The 2019 LAS Artificial Intelligence/Machine Learning team works in two broad areas. First, the analytic integrity group works to advance ML pipelines and workflows, accelerating the development and deployment of ML-driven applications and ensuring that end users can rely on the results they produce. Second, the applications group applies ML techniques in support of analyst research questions, advancing the state of the art in technology enhanced tradecraft.
