Aristo A.I. scores 'A' on 8th-grade science test

Could you score an'A' on an eighth-grade science test? If so, you're in the same league as Aristo, an artificial intelligence system whose remarkable language and logic skills highlight recent progress in the A.I. industry. For context: Four years ago, some 700 computer scientists competed for $80,000 to develop an A.I. that could merely pass an eighth-grade science test. None scored higher than 60 percent. But now, thanks to improved "language models" driven by neural networks, systems like Aristo are becoming much better at predicting language and understanding how to apply it to solve logic-based tasks. Aristo, as The New York Times notes, is built on a neural-network technology called Bert, developed by Google.
