AI: Proposal to establish an informal working group
Reference Number: WP.29-195-20
Proposal to establish an informal working group to perform a literature review of existing available standards, research, best practice and horizontal regulations relating to the use of artificial intelligence, develop a best practice guidance document for the use and operationalization of artificial intelligence such as machine learning in automotive safety systems, report back to WP.29 with a recommendation for publication of the guidance, and consider the need for further work.
