A new generation of artificial intelligence that provides a "confidence rating" of its answers could make algorithms more trustworthy and speed up their rollout in safety-critical situations. Scientists developing the technology called "uncertainty-aware AI" say it removes the risk of hallucinations - fictitious answers created by computer algorithms when they have incomplete or conflicting data.
