In February 2020, researchers from Stanford University and New York University submitted a report to the Administrative Conference of the United States (ACUS). The report, titled "Government by Algorithm: Artificial Intelligence in Federal Administrative Agencies", sought to "provide a first-of-its-kind snapshot of the current state of federal government development and deployment of AI". The report documented 157 AI use cases across 64 agencies. In December 2020, Executive Order 13960 was introduced, requiring all federal agencies to prepare and publish an inventory of its non-classified and non-sensitive use cases of AI, including current and planned uses, consistent with the agency's mission. 3 years on, our aim is to create a comprehensive catalog of Artificial Intelligence/Machine Learning use cases, across an extensive number of federal agencies.
