人工智能，机器学习都离不开数据，没有数据再好的算法，再好的模型也没有用武之地。数据不仅仅你现成数据库，它还包括每天海量剧增的互联网数据。数据获取这门课以多个项目手把手实战将系统讲解通过不同渠道获取数据，包括爬虫技术。
The modern AI foundation is machine learning and deep learning, machine learning and deep learning are based on data. The mathematic model and algorithms of AI would be useless, unless we have enough corresponded data. 
Peter Norvig is a super star in AI industry, he has developed many google products with AI. And He says that: We don’t have better algorithms. We just have more data. It conveys that so many cool google products are driven by data. So, you can see how important data is. We will introduce you a various ways of getting data from different sources in this course so that you can have enough data to train your machine learning model or data analyze.
