How can AI ethics guidelines be put into practice? With seven workshops, numerous discussions and many practical exercises, 13 leading representatives of international software-developing companies who participated in the roundtable series on ethical AI development by Stiftung Mercator and German Informatics Society created three prototypical concepts for reinforcing the responsible design of AI. A test procedure that makes corporate needs and measures comparable. A compilation of information on the topic of AI ethics, including tools, templates and good practices for responsible AI. And event formats that promote exchange and knowledge transfer within and outside the AI community. Details can be found here (German only). A final, bilingual publication will follow in November.
