Engineering giant Rolls-Royce has made an ethical artificial intelligence (AI) 'breakthrough', which it believes could contribute to gaining society's trust in the technology on the path to'Industry 5.0'. The firm has unveiled a workable, peer-reviewed AI ethics framework, which is a method that any organization can use to ensure the decisions it takes to use AI in critical and non-critical applications are ethical. The framework, which has been reviewed by several big tech firms -- as well as experts in the automotive, pharmaceutical, academic, and government sectors -- will be published under Creative Commons license this year. The framework includes a step-by-step process for ensuring the outcomes of AI algorithms can be trusted. A five-layer checking system focuses on the outputs of algorithms, not the algorithms themselves, which are constantly changing.
