If you are in the business of conversion, this issue involves the span from engineering to scientific research, engineering is important to the design of the architecture, scientific research is concerned about the mathematical model, the need for a solid theoretical foundation; if you are exploring the relationship between data and intelligence, it can be said that the current artificial intelligence are data-driven, in common parlance, it is to learn the laws from the data, the more the data the more you learn the complexity of the law, such as the depth of the law, the data is the cognitive environment. learning, data is the cognitive environment, of course, the extension of big data is too wide, not just any data can be used as learning, whether supervised or unsupervised.
