Big Data.

During the fourth Shiji tour of the country, breakfast time was filled.

June 16, the author of the "Big Data" in China Merchants Bank Shenzhen headquarters building and Ma breakfast. Ma has just stepped down as the president of China Merchants Bank, not long ago, his photos appeared in the film "Chinese partner," The end of the tribute to the trailer, and he joined the big screen entrepreneurs also include Liu, Wang Shi, Ma Yun and other people.

"The future of the world must be the data of the world, the future of the city will certainly be a data city." "During the one-hour breakfast meeting, MA The idea several times to Shiji.

In fact, since the publication of the big Data last July, when the Chinese programmer who worked in the United States returned home, it would be enthusiastically sought after. The day after breakfast with MA, he conducted a lecture on the topic of "education and large data" in Changzhou, Jiangsu Province, with more than 1000 listeners, the organizer of which was the local director of education. He also had a lunch with chairman Wan Jianhua of Guotai Securities Co., who told him that in his new book, "The Age of Financial e", a whole chapter was on the issue of big data.

"From an understanding point of view, this year can definitely be called China's big data." "Shiji said. Over the past year, including his big data, more than 20 new books on Big Data have been published in China, and some of the best selling books have even been labeled "limited purchases" on Dangdang.

If the total amount of data expected to be stored worldwide in the 2013 is recorded in the book, these books can cover the entire United States 52 times

Shiji's first public speech at home was invited by Ma. At the seminar of the National Governor of China Merchants Bank last October, Shiji, who had arrived from the United States, was pulled to the venue and 4 hours of data were spoken in front of more than 100 branch governors.

"What is the big data?" "The most curious of the governors from all over the country is the question.

According to Shiji, this first is a new description of the age of information explosion. In fact, if the total amount of data expected to be stored worldwide in 2013 is recorded in the book, then these books can cover the entire United States 52 times. If the data is stored on a CD-ROM, these discs can be stacked into five piles, each of which can reach the moon.

In fact, in the great data age, the Internet expert Victor Maire-Schoenberg's book, the data stream of the Internet era is relatively comparable to the explosion of information caused by the invention of the printing machine before and after 1439, and one important finding is that "it took 50 years to increase the storage volume, And now it can grow by one times every 3 years.

But in Shiji's view, only a large amount of reading data is biased, the energy is large data on the other side of the coin.

A classic case in point is that, in the weeks before the swine flu outbreak, Google found that the subject of "drugs to treat cough and fever" had seen a significant increase in the number of searches for 50 million of Americans ' most frequently retrieved entries, which accurately predicted the onset and spread of influenza.

"In the face of massive data, who can better deal with, analyze data, who can really rob Big data era of opportunity." "The perennial living in the United States is impressed by the power of large data, he remembers once he wants to move, then put all kinds of furniture in the online auction, the result is soon move company to come to the door."

Similar to Shiji's view, a Chinese student studying for a master of statistics in the United States also told reporters that big data were very hot in the United States. He clearly remembers that there was a case on the PPT in the classroom--the United States has a booking website called Orbitz, who, through data analysis, found that the price of customer bookings is often related to their web browsers, with the highest safari, Chrome and Firefox. They make adjustments so that once a user logs on through the Safari web page, they tend to be given high price search results.

In fact, in a report published by McKinsey, data analysis has been described as "the next frontier for innovation, competition and productivity".

You want to use more than 3,000 samples to refract Gui user behavior, this is not absurd to say

In the United States, data analysis formed a complete industrial chain, many universities also set up a related master's degree, and in China, such a missionary is like a prairie fire. Last year, an angel investor named Wang Yuquan once spoke to Shiji, like Shiji, a faithful believer in data, "The entrepreneur who is now going to vote must have data analysis technology, otherwise it will not be discussed".

In Wang Yuquan's view, in traditional sociological studies, "large samples, real-time monitoring, continuous monitoring" is often not a condition, and large data to break the myth.

"We all know that CCTV Sofres is doing TV ratings survey, we know how many samples?" More than 3,000. You want to use more than 3,000 samples to refract Gui user behavior, this is not absurd, needless to say. He said in a speech, "web2.0 changed the status quo, whether on Facebook, Twitter, Sina Weibo, micro-letters, we can always get full sample real-time continuous data, this time our understanding of user behavior is likely to reach unprecedented depth." For example, when there is no social network, a famous person has always said that he is a Caltech graduate, people believe for a long time, and so there are social networks you look at his friends, there must be a number of Western Pacific and not Caltech, you guess where he graduated? ”

In the big Data age, Victor Maire-Schoenberg has put forward another important argument that, in contrast to causation, relationships may help us better understand the world, in other words, knowing what "is" is more important than knowing "why" in the age of large data. A classic case in point is that Wal-Mart researchers, through data mining, found that about 40% of young dads would buy a baby diaper to reward themselves by buying a beer, then bundling the two goods together, resulting in an increase in sales.

"What's the most lethal thing about big data?" Is any data I can sum up, analysis of you, than you know yourself. "Wang Yuquan once interpreted the value of large data.

Shiji remembers that last October, when he was a member of the Politburo, Guangdong provincial party secretary Wang Yang had recommended the "big data" to all cadres of the provincial finance department. Wang said that the data is competitive: "You can not think of the whole Chinese bikini selling the best of which provinces, the general people believe it is definitely Guangdong, Hainan Island." ”

Ma Yun immediately told Wang Yang, from Taobao data to see, in fact, the best selling is Xinjiang and Inner Mongolia. He explains this anomalous correlation: it is estimated that every man should give his wife, lover and object a beautiful vision, "One day I will take you to the sea."

"Of course this is one of his explanations, but what can be reflected is that the data is not a concept as you think." If the merchant mastered this thing, in fact, your bikini advertising focus do not put in Guangdong, you put in Xinjiang, Inner Mongolia to do ah, this effect may be very different. Wang Yang gave his own interpretation.

In China, big data will change our lives

This time, Guangdong, who has worked for many years, is still a Shiji. These two days, in addition to meeting with MA, he also and several managers of Citic Bank made in-depth communication, let him feel that the financial "elites" no longer regard large data as a novelty concept, but began to have some "deep concern."

The imaginary enemy of the financial giants is the Internet enterprise that holds a lot of data. Once two times to Alibaba exchange Shiji told reporters that Ali finance is trying to solve the "small micro-enterprise financing difficult" problem through large data technology. "All loans are financed by credit, unlike banks that require property or other collateral, and do not require interviews." Because they will be the customer's all behavioral data mining analysis, and then decide whether to lend. ”

"It is hard to imagine that it can become a bank by relying on large data technology," he said. Shiji smiled and said, "in China, big data will change our lives step-by-step." ”

In fact, more and more ideas based on large data technology are actually entering the lives of Chinese people. There have been media reports of Alipay's data that scientists work on a daily basis: they will be divided into 50 groups of customers to study, including a group called the City of Light ripe male, there is a group called daughter of the United States girls, and these types of classification is based on Taobao, Cat, Alipay and the cost of the paid behavior data. A subtle change after the user is identified is that it is no longer the same as using the "pro" as it used to be when writing a product's recommended text.

Similar changes have been Shiji. Once in the domestic speech, he lived in the White Swan Hotel, the hotel's information department director told him that the hotel's information department has the habit of collecting water consumption. One year, the original smooth water consumption suddenly appeared sharp fluctuations, the staff after analysis and investigation found that there is a pipe under the flower bed for a long time, "is the data so they found the problem."

This time, another story about the big data makes his eyes bright. In east China Normal University, a girl because of weight loss, May meal card consumption less, unexpectedly received a system message: "Hello classmate, found that you eat less food last month, do not know whether there is financial difficulties?" If you have difficulty, can telephone, text message or mail me. If there is no difficulty, please reply, so that the inquiry will not be repeated next month. ”

Originally, the news from the school's difficult health warning system, and this system is based on student rice card consumption data built. Shiji the first time to comment on this tweet: "ECNU use data to express love and care." ”

In a speech, Shiji once said: "Today, the data has been everywhere, our daily necessities, joy and sorrow, eat and drink are in the form of data." Through data, networks, and software, we use data to record the world, and then to discover the world through research data. ”

"Big Data everywhere?" The reporter asked Shiji on the phone.

"I think so, oh, guess what I looked up and saw?" Shiji, who is preparing to go to the next address at Baiyun Airport, told reporters that there was a big IBM ad in front of him that said,

Large data Age: the wisdom of the analysis of insight, the construction of intelligent Earth.
