The establishment of shared theoretical frameworks, combined with the availabil- ity of data and processing power, has yielded remarkable suc- cesses in various component tasks such as speech recogni- tion, image classification, autonomous vehicles, machine translation, legged locomotion, and question-answering sys- tems.
