Data Science Tutorial

当今世界由数据主宰。这引发了对数据科学家的特殊需求。无论你使用搜索引擎获取互联网上的信息，还是询问你的移动设备获取路线，你都在与数据科学应用打交道，所以我们已经以多种方式接触到了数据科学。数据科学在多年来处理我们的一些最日常活动中起着重要的作用。如果你对数据科学有很好的了解，你将能够以最有效的方法处理数据。

The world is now ruled by data. This has caused an exceptional need for Data Scientists. We have already encountered data science in various ways, whether you use a search engine to get information on the Internet or ask your mobile device for directions, you are engaging with data science applications. Data Science has been important in handling some of our most routine everyday activities for numerous years. You will be able to handle the data in the most efficient manner if you have a good knowledge of data science.

数据科学也被称为数据驱动科学，其利用科学方法、流程和系统从各种形式（即结构化或非结构化）的数据中提取知识或见解。数据科学使用最先进的硬件、编程系统和算法来解决与数据相关的问题。这是人工智能的未来所在。

Data Science is also known as data-driven science, which makes use of scientific methods, processes, and systems to extract knowledge or insights from data in various forms, i.e. either structured or unstructured. Data Science uses the most advanced hardware, programming systems, and algorithms to solve problems that have to do with data. It is where artificial intelligence is going.
