1、Hello, everyone. As we all know, we are now living at the age of big data, which leads a revolution that transforms how we think. But many people have half know of big data, they havent adopted to the tremendous change. So today Id like to talk about the three peculiarities of big data. I will be ve
2、ry glad if my speech could help you.Firstly, all samples rather than sampling analysis. With the development of technology, we are able to process massive data, from which we can get more reliable result than through sampling analysis. So we can give up sampling analysis in most cases.Secondly, effi
3、ciency rather than accuracy. At the age of big data, we concern more on efficiency rather than accuracy. In other words, we should allow faults to improve efficiency. Comparing with massive data, some faults do not influence the final result.Thirdly, correlation is as important as causality . We can
4、t deny the importance of causality ,but sometimes it is difficult or unnecessary to explore it. For example, the recommendation system of Amazon doesnt know why the customer who likes Hemingways works is likely to buy Fitzgeralds works, it just recommends and helps Amazon sell more than 100 times books than before Amazon using it. From this example, we can conclude that correlation plays an important role at the age of big data, so please dont overlook it.Finally, lets review the three peculiarities of big data. Please remember them, maybe they will help you one day.Thats all, thank you.
