Big data requires great wisdom.

In the August 31 held a large big dialogue Baidu, director of the IT Human Power Laboratory, "father of wearable equipment", Alex Pentland, one of the world's top seven authoritative data experts, briefed participants on recent advances and reflections on artificial intelligence and large data, which also sparked a new round of social attention to big data.

Large data has been developed in the domestic application boom

In the last two years, the concept of large data has been very hot in China, and applications have been pushed forward, most notably in Brazil's just-concluded World Cup match forecast. In other respects, big cities such as Shanghai make use of large data for intelligent traffic management, and some electric business websites also use large data to conduct customer behavior and purchase forecasts, which improves the level of fine marketing.

The most important data companies in the country, to bat three internet giants as the most, Tencent has hundreds of millions of social users of the exchange of information, Alibaba has hundreds of millions of users of the transaction behavior data, Baidu has mastered the Chinese Internet users most concentrated search behavior and traffic point data, so, These companies have a good foundation for large data applications.

Baidu as an example, Baidu's World Cup data forecast in Brazil during the World Cup to help a lot of people better watch the game and predict the results, and the Baidu sticky Rice "exclusive" service is to create a large data interesting application of the classic. Of course, the cooperation between CCTV and Baidu during the Spring Festival, the analysis of passenger flow during the Lunar New Year makes many people feel the power of large data for the first time, and the United Nations to start strategic cooperation to build large data joint laboratory is to create a precedent for the United Nations Development Programme.

What is big data? Data acquisition capability is critical

According to Wikipedia's explanation, large data, or huge amount of data, refers to the volume of data involved is too large to pass the current mainstream software tools, in a reasonable time to achieve capture, management, processing, and collation to help the business decision-making more positive purpose information.

Even so, there is still no universally acceptable definition of big data. It can be said that the large amount of data is not large data, and then a large number of data, if can not be used can not be called large data, and a single domain of a large number of data collection is not really large data. According to general understanding, large data should be the integration of seemingly irrelevant data around a particular topic to form a unified view, and then find the reasonable correlation factors during the period, thus exceeding the simple statistical analysis and drawing unexpected conclusions.

Professor Alex Pentland points out several areas where large data applications are more successful, including marketing scenario prediction, urban management, disease prediction, financial forecasting, and so on, which rely on massive data accumulation and different customer scenarios, and Internet search engines have innate advantages.

Baidu is the world's most populous country's largest search engine, has recently been actively strengthening the international layout, just a high-profile entry into the Portuguese-language market, more than 10 years to accumulate a large number of data, which is unmatched by other Internet companies advantages. Big data, more significance is: human can "analysis and use" of data in a large number of increase, through the exchange of data, integration and analysis, human can discover new knowledge, create new value, and let a lot of normal cognitive, judgment, thinking set, product form, service mode, To form a new face and direction of evolution.

Obviously, Baidu is for the whole network users of all aspects of the use, so the data in these fields are the most complete companies, the most capable of launching large data areas of exploration. Through the analysis of large data, Baidu realized from the search information to search the product changes, but also in the data use of innovation.

Big data not only "big", but also need advanced data analysis and application ability

At home, there are a lot of data companies, such as banks, airlines, telecommunications operators, but these companies are not enough data use, limited to the structure of the system and personnel issues, so far in the large data has only just begun.

The internet in this respect has been the first, Tencent Ali has its own large data application development team, Baidu in early 2013 set up the Baidu Institute, which is the first focus of the direction of in-depth learning, and for this reason the establishment of Cato of Deep Learning (IDL), As a leading research organization in the field of large data, Baidu has made a good preparation for the two years ' progress in large data field. The World Cup forecast model is also the in-depth study by the Baidu Research Institute to send senior data scientists to assist the large data research team to build together, the team stage of the prediction success rate of 58.33%, the knockout phase of the full forecast accuracy.

According to media reports, Baidu's in-depth study institute attracted a large number of world-class technology elites, such as former senior Facebook scientist Xu, Professor Zhang Yi of statistics at the State University of New Jersey, and the "father of Google Brain" to join the Wunda.

Large data applications also need carriers, not known as roots

The millet mobile phone, Tesla's electric cars, video Super TV, Haier's air box, the boom-triggered Microsoft ice, the hit card house and other products, they and traditional innovative products do not appear to be very different, but behind the fact that there are large data applications shadow. To big Yue City for example, when consumers want to go to a merchant, Baidu will pass large data storage and analysis told him, the merchant in a few layers, how many people inside, consumers want to leave the shop, Baidu Map will guide specific routes, how to go to the car park, more accurate to find from the car.

The value of large data to be reflected through the corresponding products, for example, smart wearable equipment can not be separated from the application of large data, otherwise it will become lifeless toys. In the use of large data, the domestic more mature areas including the Internet financial Risk control, online shopping area of intelligent recommendation and Internet traffic management, more successful products have Alibaba balance treasure, plump smart hand ring, Baidu Index, such as the Baidu.

In the application of large data, Baidu can be said to spare no effort. In fact, Baidu has already gone beyond search, become a collection of Web pages, bar, pictures, know, news and other advantages of the cross-screen integrated marketing platform, covering all the key marketing users all the time Baidu through the "intimate Search + Light application + Voice search +lbs Fangyuan positioning Technology" and other technologies, Baidu is trying to achieve " Let search engines be as intelligent as the human brain. Data show that in 2013, Baidu net profit of Two-thirds spending with a "scientific and technological sense" of mobile projects, smart bracelet, smart watches, electronic scales and so on are involved, but also said to develop unmanned bicycles.

Generally speaking, the development of large data needs a solid application, not always play the concept, more need to accumulate resources to upgrade the level of technology, data storage, data analysis and application of the scene constantly blaze new trails, so can really touch the soul of large data.
