Nowadays, a new round of technological revolution and industrial transformation is rising, which promote the rapid evolution of digital technology represented by artificial intelligence, and human beings are marching into an intelligent society. According to the White Paper on the Core Technology Industry of Artificial Intelligence, released by the China Academy of Information and Communications in April this year, AI has fully covered the basic elements of social operation and improved overall operating efficiency. In the future, AI will be as ubiquitous as water and electricity, disrupting and transforming every industry.

Data play an important role in supporting the development of artificial intelligence. Artificial intelligence model needs massive data to train and optimize. Among the three core elements, data, algorithm and arithmetic power, the focus is changing from algorithm to data. Data sets the upper bound for machine learning, and only when data is valued by developers, more accurate models can be trained. Enda Wu, a leading machine-learning expert, argues that machine learning will evolve rapidly if more emphasis is placed on data rather than model.
