Big data life: there are hi also worry

The ubiquity of vast amounts of information has now begun to change the world and daily lifestyles, a revolution that comes from big data quietly coming. Big data has the potential to be a reality by controlling and managing all aspects of our future life.

Professor Victor Michael Schoenberg of Oxford University, hailed as "a prophet of the big data age," described the impact of big data on our lives as a "change."

Many people have had this experience - just opened the microblogging, the web gave you recommend some "you may know," and these people inside, there are really many of you lost contact for many years friends, classmates; Open the shopping website, where you actually find some items you are planning to buy on the recommended shopping list displayed on the web. Open the news site and the system's recommended news center your appetite.

Actually, all these rely on "big data technology." These websites analyze your preferences, social circles and even lifestyles by analyzing numerous data such as your browsing habits ...

Win the decision from big data

Successful prediction of the outcome of the presidential election

Last year in the U.S. presidential election, data expert Nate Silver successfully predicted the winner and the winner in almost every state on the basis of big data. When Obama and Romney sentiment were generally considered very close, commentators were unable to predict which side would win and Silva calculated the "real" situation based on the findings of the major pollsters' ongoing updates in the states, Pointing out that the two are not in a good match. On the polling day, he successfully predicted that Obama will have a 90.9% chance of getting the majority of votes, and finally his prediction of the voting results of the 50 U.S. states is all right.

In fact, Silva also predicted the final result in the 2008 U.S. presidential election. He predicted 49 votes for the 50 U.S. states.

Predict the time and place of crime

Many public service agencies, especially the police and security agencies, are also beginning to enjoy the benefits of big data. Some cities have used big data to figure out the chances of crime in certain neighborhoods. One of them is Santa Cruz, California.

The Big Data algorithm can figure out the odds of a crime happening anywhere (house burglary, robbery, car theft, but not killings) at some point in the past two years, when about 100 patrolmen in the city were targeted for patrolling On their trips, the electronic cards carried by them will show the 15 most-likely crime places nearby. And in two-thirds of cases, the big data algorithms predict the crime did happen. According to Clarke, director of the city's police department, the introduction of this big data algorithm reduced the number of burglaries in the city by 11% and the number of car thefts by 8%. Correspondingly, the success rate of arrests increased by 56%.

At present, more than 10 police stations in the United States have introduced this big data algorithm, including Los Angeles, Boston and Chicago.

Blind date, cure it by

In addition to generating profits for businesses, big data can bring other benefits to human society.

For many, the most intimate aspects of their lives have also begun to rely on the predictive power of this mechanical algorithm. For example, many online dating agencies will ask you to fill in a very detailed questionnaire and then increase your odds of finding the other half based on the big data algorithms.

Earlier this month, the UK's first medical and health research center to integrate big data technology was founded at Oxford University. According to reports, the research center through the collection, storage and analysis of a large number of medical information to determine the direction of the development of new drugs, thereby reducing drug development costs, while providing clues for the discovery of new treatments.

Researchers at the University of Manchester in the UK are working on a "magic carpet" for the elderly living alone. The "magic carpet" looks like an ordinary carpet, but filled with sensors to record the footsteps of the elderly, the data will be uploaded, the computer can be compared with the health of the elderly, and then tell whether the elderly Emergencies need medical attention, if so, it will automatically trigger an alarm.
