Beware of "fortune-telling" in the guise of big data.

The word big data has entered a new climax after the World Cup frenzy, with the German team using large data analysis to enhance the player's ability and adjust the strategic deployment. Finally, the news of the win, the industry is elated, as if the future "prediction industry" will be ambitious.

However, in Baidu, Google and other technology companies preach large data analysis accurate science at the same time, the author seems to have seen the year http://www.aliyun.com/zixun/aggregation/30071.html "> The insurance salesman sold himself the insurance scene. They always list the benefits of the current business, and a variety of High-yield returns are exciting. But when the author asked to see the contract, they said that only when the contract was signed to see. Later, they finally set up a little bit of the truth of the insurance, such as their commitment to the high yield you have time requirements, many are more than 10 years or even more than 20 years before they can be taken out, if you want to take out, then the proceeds may be similar to the bank regularly. And he promised the various accident protection, in fact, there are ordinary people did not notice the restrictions and language of the game. Ambiguity between, is actually put those rights and interests back. Investors who want to be cheap will, in fact, be more likely to end up paying a little more than a bank, and have not achieved the investment goal.

This is like telling you all the benefits of venture capital, but not telling you that you'll lose a lot of trouble when you have a problem. Evasive tactics, is now a lot of irregular domestic insurance, funds, financial investment practices.

Now, this approach seems to be used in large data analysis. Like the Brazilian-German game, Google calculates Brazil's 69% win. When the game was over, everyone thought Brazil was winning. However, the result, but a pot of cold water. Yes, big data forecasters will always emphasise what they've been predicting in the past before the outcome of the event, and then preach that the results are accurate.

In fact, the author can not prove that the 69% win in the end is right or wrong. But a very simple truth: 10 signed 7 red, may not necessarily be able to smoke in red.

So when Google is full of confidence, it gets a blow.

Of course, the starting point for some tech companies that do big data forecasts is not to deceive users, they calculate trends and probabilities, but they themselves get caught up in the cold data and forget the 31% chance of failure.

In fact, it is because of the crushing ego of these tech giants that the author fears: Will there be small data companies that do not have the ability to do large data analysis, or that they have only rudimentary data analysis capabilities, and then advertise themselves as "Big data analysis" as a result of the "big Data" boom, to get a scoop? It is even possible that people who do not understand large data analysis, under the banner of large data, boast their own analysis of "science", "accurate", misleading and deceive ordinary users!

In fact, not only in China, even in large data analysis of the more mature European and American countries, but also some people will fall into the great data brought about by the brilliant. As if there is big data, everything is solved. Film is not a problem, competition is not a problem, not even the future is not a problem. Eventually a movie is like the same mold card out of the game lost passion only to analyze the data of the mechanical implementation, and the future ... Who knows?

I would never deny the good guidance of big data, because the Germanic chariot that swept South America into four-star Germany proved that the team would reap fruitful results by correctly using large data analysis. From Germany I learned: How to use large data, is the most we need to face up to the problem.

Big data forecasts are not wrong in themselves, but if they become big data "fortune-telling," then the cart is reversed.

Vaguely remember the rise of the computer stage, in the amusement park saw a "fortune teller machine", advertised himself as "Science fortune-telling." It was funny. But now the big data analysis, is not going to become that "fortune-telling machine" ...
