In his book "The Age of Big Data", he said that in the past, once the purpose of collecting data was completed, these data would be considered useless. For example, after the plane lands, the fare data is useless; After the completion of a network retrieval command, this command also entered the past tense.
But now, data has become a kind of commercial capital, which can create new economic benefits. Data can be a kind of capital, which is closely related to the mobile Internet.
With the "cabbage" of mobile digital products such as smart phones and tablet computers, Wi-Fi signals are everywhere, and more and more people no longer have the distinction between "online time" and "offline time". As long as they want, they can be online almost 24 hours a day. The popularity of online trading, online payment, online registration and other network services facilitates users, but it also makes people more dependent on the network and various network platforms. With the development of science and technology, information that used to need several boxes of floppy disks or a CD can now be stored in a chip the size of a fingernail, which is more than enough. In the past, digital information carriers that needed computers, monitors, card readers and other special equipment to read, now only need a smart phone and a free download of third-party applications, you can see the data at a glance.
Scientific and technological progress in the era of big data has turned more seemingly ordinary things into "mobile databases", such as second-generation bank cards with memory chips, credit cards, new passports, driver's licenses, social security cards with chip reading functions, library cards and so on. In some developed countries, in order to facilitate information input, the government has continuously combined the functions of various "mobile databases" into one.
The digital age makes it more and more convenient to collect, summarize and analyze information. Traditional random sampling was replaced by "collecting all data". Some attributes that become important based on random sampling, such as sampling accuracy, logical speculation and reasoning judgment, become less important. It is very important to collect as much data as possible and draw trends and conclusions based on these data. To put it simply, in the past, the thinking decision-making mode was based on "why", but in the era of "big data", conclusions can be drawn directly from "what". Because this conclusion excludes the interference of personal emotions, psychological motives, sampling accuracy and other factors, it will be more accurate and predictable.
However, some scholars have pointed out that because the theory of "big data" relies too much on the collection of data, once there is a problem with the data itself, in the mode of "only asking what is there, not asking why", "catastrophic big data" is likely to appear, that is, making wrong predictions and decisions because of the problems with the data itself. If I can help you, I hope you can adopt it! ! E69DA5E887AA323131335323631363533313339666665438 Thank you! ! )。
2. Human brain and artificial intelligence composition Artificial intelligence is coming. Some people are worried about unemployment, some people are looking forward to the future, some people are exploring industry opportunities, and some people are studying Go.
Before discussing these, maybe we should consider the end of mankind first. Some people may think that talking about this topic is too exaggerated, so let's first recall what incredible things have happened in human history.
Incredible things need to be judged by several travelers. We invite 1 people (Han people) born in 0 AD to cross to 1600 AD (Ming Dynasty). Although they crossed 1600 years, this man may not feel too exaggerated about the life of the people around him, but he has changed several dynasties and still lives with his back to the loess.
However, if an Englishman of 1600 1 is invited to cross to 1850 England and see a huge steel monster running around on the waterway, this person may be scared to pee directly, which was unimaginable 250 years ago. If people from 1 with 1850 are invited to cross 1980, it is said that a bomb can level a city, and this person may be directly scared. Nobel did not invent explosives before 130.
How about inviting 1980 to 1 person now? Will this person be scared to cry? If it is hard for people to imagine life in the Internet age 35 years ago, then how can we imagine that human civilization has entered the era of exponential development 35 years later? Super artificial intelligence is the ruler after 35 years. First of all, let's clarify the classification of artificial intelligence: at present, there are three categories of mainstream views.
Weak artificial intelligence: weak artificial intelligence is artificial intelligence that is good at a single aspect. For example, an alpha dog can beat humans in Go, but when you ask him who is more handsome, Li Shishi or Ke Jie, he can't answer.
Weak artificial intelligence depends on the computer's powerful computing power and repetitive logic. Seemingly clever, in fact, he can only do some precise physical work. At present, there are many weak artificial intelligence in automobile production lines, so in the era of weak artificial intelligence development, human beings will indeed usher in a wave of unemployment and find many new industries.
Strong artificial intelligence: human-level artificial intelligence. Strong artificial intelligence refers to artificial intelligence that can compete with human beings in all aspects. It can do all the mental work that human beings can do.
Creating strong artificial intelligence is much more difficult than creating weak artificial intelligence. Baidu's Baidu Brain and Microsoft's Xiao Bing are both explorations of strong artificial intelligence, helping strong artificial intelligence to learn gradually through huge data.
With the advent of the era of strong artificial intelligence, human beings will have a lot of new fun and new moral concepts. Super artificial intelligence: surpassing human artificial intelligence in all directions.
Super artificial intelligence can be a little stronger than human beings in all aspects, or it can be a trillion times stronger than human beings in all aspects. When artificial intelligence learns to learn and correct itself, it will continue to accelerate learning. This process may or may not produce self-awareness. The only certainty is that its ability will be greatly improved, including its creativity (Alpha Dog will adjust its strategy according to the chess player's moves, which is the most superficial innovation. The ordinary mobile phone version of Go and computer chess are actually fixed).
How far are we from the era of super artificial intelligence? The first is the computing power of computers, which doubles every two years, which is supported by historical data. At present, the computing power of the human brain is 10 16 cps, with 65438+ billion calculations per second.
Now the fastest supercomputer, Tianhe II in China, has actually exceeded this computing power. At present, the computing power of the computer we ordinary people buy is only one thousandth of that of the human brain.
It still sounds weak, but according to the current development speed of electronic equipment, we can buy a computer that can compete with the computing speed of the human brain for 5000 RMB in 2025. The second is to make the computer intelligent. At present, there are two attempts to make computers intelligent. One is to do brain-like research.
Now, we have been able to simulate the brain of 1 mm flatworm, which contains 302 neurons. The human brain has 654.38+000 billion neurons, which sounds far from it.
But please remember the power of exponential growth-we have been able to simulate the brains of insects, the brains of ants are not far away, and then the brains of mice. At that time, it is not so unrealistic to simulate the human brain. The other is to imitate the learning process and let artificial intelligence constantly correct.
Based on the huge data generated by the Internet, artificial intelligence is constantly learning new things and constantly correcting itself. Baidu's Baidu brain is said to have a 4-year-old intelligence, which can have several continuous conversations and judge a person's movements according to pictures.
Although there are still many mistakes, the change of this ability is a qualitative change. In the eyes of the smartest scientists in the world, the emergence of strong artificial intelligence is no longer a question of whether it will happen, but when it will happen. There was a survey on 20 13, and hundreds of artificial intelligence experts participated. "When do you predict that human-level strong artificial intelligence will be realized?" The results are as follows: in 2030, 42% of the respondents think that strong artificial intelligence will be realized in 2050; 25% of the respondents think that strong artificial intelligence will be realized in 2070; 20% of the respondents think that it will be realized after 2070; 10% of the respondents think that it will never be realized; 2%, that is to say, more than two-thirds of scientists think that strong artificial intelligence will be realized.
Most importantly, the world's top elites are abandoning the Internet and turning to artificial intelligence-Stanford, MIT, Carnegie Mellon, Berkeley's first offer of artificial intelligence doctoral students can already get 2-3 million US dollars. This has never happened in history.
Kurzweil, president of Singularity University (co-founded by Google, NASA and some science and technology experts), has a more optimistic estimate. He believes that computers will achieve strong artificial intelligence in 2029 and enter the era of super artificial intelligence in 2045. So, if you think you can live for 30 or 40 years, you should be able to witness the emergence of super artificial intelligence.
So, with the emergence of super artificial intelligence, what is the end of mankind? 1, extinction-the usual law of species development can easily reach the end of 1, and super artificial intelligence can happen as long as it faithfully performs its original task. For example, when we created artificial intelligence for a traffic indication system, the initial programming logic was to use big data.
3. How to write a 600-word artificial intelligence composition? The era I live in is the era of "artificial intelligence", which is an unprecedented change compared with the history before mankind!
Since 1956, when scientists first put forward the term "artificial intelligence", after nearly a hundred years of development, "artificial intelligence" has now opened a new era of human life.
If you don't know much about artificial intelligence, let me show you this great technology through my day's life.
At home at 7: 00
Birds are singing in my ear, and I smell the smell of dew grass. I slowly opened my eyes and saw a holographic projection of the early morning forest. I got out of bed barefoot, and the little white rabbit and deer were playing beside me. When I come to the bathroom, the temperature and humidity here are controlled at the most appropriate values. I was lying in a chair in the bathroom and chose the No.2 cleaning button: one robotic arm cleaned my mouth with an electric toothbrush, the other robotic arm cleaned my facial skin, and my hair was cleaned and cared for. Breakfast has been prepared in the restaurant. Today's breakfast is a plate of mango caviar, a five-layer cake and a small bowl of fresh blueberries. Mango caviar is made by rapidly cooling mango juice with liquid nitrogen at-196℃ and wrapping it in edible capsules. With a gentle bite, mango juice instantly fills the mouth. Five-layer cake is a masterpiece of 3D food printer, each layer has a different taste and rich taste.
With the development of science and technology and social progress, a new generation of information technology such as artificial intelligence AI is vigorously building a smart life, and the Internet, smart phones, LCD TVs, air conditioners, etc. are gradually entering thousands of households in Qian Qian.
1977 the manager of the world's largest internet company in Britain predicted that no one would have a computer of his own at home in the future. Computers will not be used by most people, but in the rapidly developing modern society, it is almost impossible not to use computers. The staff in the high-rise building are using computers to record the tasks assigned by their superiors. The cartoonist is scanning and coloring the draft with a computer; There is one in every classroom in the school. Teachers use computers to explain the texts to students. The computer in the print shop is busy working. However, the manager never imagined that computers have played an irreplaceable role in our lives for nearly half a century, from the bulky machines that filled a whole room to the thick liquid crystals in textbooks.
The future, an abstract synonym-can't touch, can't feel. Everyone has a beautiful imagination, and I imagine the bright future of the city. The beauty of the city is bound to be accompanied by neon lights. The bustling night scene and the busy people's market. What is behind the prosperity? Is it dark? No, there is at least one lamp. Is it the home of those homeless people? No, at least there's a cabin. Although light is beautiful, darkness will be illuminated by countless bright lights. I imagine, imagine the tranquility of this city.
When people start their day's work against the rising sun, their mood is calm and happy. At this time, bicycles have become "antiques" and people can only see them in museums. On the wide and modern overpass, luxury cars shuttle back and forth. In residential areas, property management is a robot with 24-hour service. The workplace is not as narrow as it used to be. It is no longer just a computer that works alone, but an office for two or three people. Without cameras and monitors, people are honest, trustworthy and diligent. A factory is where robots work.
We pile up beautiful dreams layer by layer. Let's look at the forefront of the times, look at yesterday, look forward to the future, and approach the place we yearn for step by step along the Cotai Strip. Let's imagine a better tomorrow and move towards a better future!
In fact, happiness is very difficult! When darkness enveloped the city, there was never that corner: someone was fighting. Is this a beautiful city? Now this heavy responsibility has fallen. On everyone's shoulders, we middle school students in the new era have even fallen on our writing. We should use pens to describe the future city and draw its most lovely and beautiful side. In our campus, confetti is very precious because it will never appear. Smiling is common because it permeates everyone's face. The beauty of a city is like building a house-the first floor is civilization, the second floor is peace, the third floor is prosperity and the fourth floor is happiness. Only by continuous construction can we cover its roof-beauty. Let's work together to build this "beautiful" city!
5. My big data composition is 600 words. How to write the first paragraph first summarizes the environment in today's data age. For example, in the era of big data, everyone has their own mobile phone. He used to just play games and surf the Internet. Now even a few cents of dishes can be paid with Alipay WeChat ... These are the conveniences brought by the era of big data. (Write the first paragraph, about 50 words. )
The second paragraph is transitional: I also have a story about big data.
The third paragraph focuses on the benefits you enjoy under the generation of big data. Briefly write down the bad problems encountered. (at least 4/500 words)
Finally, in the era of big data, everyone will inevitably come into contact with this new trend of thought in the future. If you don't want to fall behind, you have to ride the wind and waves in the times. New things are bound to be accompanied by disadvantages, and whether they can thrive depends on our attitude. The double-edged sword of big data still needs us to distinguish and make good use of it in order to better meet this era and play its role.
The meaning is similar.
6. Which big data technology is better than artificial intelligence? It is mainly a series of valuable operations around the data itself, including data collection, collation, storage, security, analysis, presentation and application, among which data analysis is an important step to realize the value of big data.
Big data technology is closely related to the Internet of Things and cloud computing. The Internet of Things provides the main data source for big data, and cloud computing provides a supporting platform for big data. Although artificial intelligence has been developed for more than half a century, it is still in its infancy. The main research fields of artificial intelligence focus on six aspects: natural language processing, knowledge representation, automatic reasoning, machine learning, computer vision and robotics.
Artificial intelligence is a typical interdisciplinary subject, involving philosophy, mathematics, computer, economics, neurology, linguistics and many other fields. In recent years, with the development of big data, artificial intelligence has also ushered in new development opportunities, especially in the field of machine learning.
Thanks to rich data support, machine learning (including deep learning) has been widely valued and widely used in the fields of autonomous driving, intelligent logistics and smart medical care. From this perspective, big data and artificial intelligence are closely related. It can be said that big data is an important foundation of artificial intelligence.
At present, many practitioners in the field of artificial intelligence also have experience in the big data industry. For example, in the process of big data analysis, they often come into contact with machine learning, because it is a popular practice to analyze data with machine learning, and machine learning is one of the main research contents in the field of artificial intelligence, so the boundary between big data and artificial intelligence is gradually blurring. From the perspective of learning, learning from big data is a good choice. On the one hand, big data-related technologies have matured, on the other hand, big data-related technologies are currently in the application stage. With the development of industrial Internet, big data will have great development space in the future.
I have been engaged in the Internet industry for many years, and I am currently a graduate student in computer science. My main research direction is big data and artificial intelligence. I will write some articles about internet technology in the headlines one after another, and interested friends can pay attention to me. I believe I will gain something. If you have any questions about the Internet, you can also consult me. Thank you.
7. How to write an example about the relationship between man and artificial intelligence?
Just after work, with a hard day's work, I gently pushed open the door. A-GO, the mechanical housekeeper of the new era, has been waiting for a long time. She prepared bath water for me, changed clothes and today's cookbook.
A-GO is an artificial intelligence, with a beautiful appearance, long blond hair extending to the waist, fair skin shining in the sun like a diamond, charming almond eyes always flashing with real eyes and sweet smile, just like the voice of nature. He is like a precision instrument on my time axis, which ensures the normal operation of my life. It's hard to treat her as a machine after being together for a long time.
When I stepped into the bathtub, my fatigue seemed to dissipate in the water instantly. "What do you think of the water temperature?" Brother asked. It would be great to take a bath with a sweet voice. "OK, no problem ~" I replied with a smile. It is a new generation of artificial intelligence, so gentle and considerate. We haven't been together for a month. A-GO seems to have a general understanding of my lifestyle and learned how to serve me. This is all due to the self-learning program of artificial intelligence.
Recalling that Alpha Go, which won several rounds of Go, was nothing in front of a-GO, I thought to myself.
Before coming to the dinner table, a-GO turned to me and once again showed the results of her self-study. Appetizers before meals, plus high-end western food, were presented to me. I picked up a knife and fork and wolfed it down. "Do you think it's delicious?" Brother asked. "It's delicious!" Forget the food you haven't swallowed in your mouth and praise it loudly. "I'm glad you like it." Brother narrowed his big eyes into a crack and showed a knowing smile. Then she went to the charging room. No wonder, she must be tired all day, but unfortunately she can't have dinner with her. I thought, by the way, put the steak in my mouth.
Hmm! Delicious!
Living together for a long time, a-GO is like a big sister living at home, which makes me extremely dependent. Gradually, my bad habits have increased a lot, and a-GO's mature learning ability has also subtly changed her.
The morning light shone into my bedroom and I rubbed my hazy eyes. What? Has it passed 12? I didn't know I was late until I picked up my mobile phone and confirmed it repeatedly. I can't imagine that a-GO didn't stand by my bed and wait as usual. Not only that, breakfast didn't appear on the table on time.
I found her in a-GO's room. She seems to be a different person. She stared at the screen of the game machine intently, and her usual dignified appearance disappeared, leaving only a lazy look. Since that time a-GO became interested in the game machine in my hand, she has been playing games more and more. Not only that, under my influence, a-GO quickly learned my lifestyle, and I soon realized that this a-GO in front of me was like a copy of me. Suddenly she said to me coldly, "Go out and buy me the latest game." I suddenly flew into a rage: "What did you do?" Seeing my dissatisfaction, a-GO took out his gun and threatened me: "Let's go!" Sure enough, this guy not only learned my lifestyle, but also copied the character I was used to these days.
A-GO is now more like a cold and cruel queen, oppressing my life. Before long, I was kicked out of my house by a-GO and had to sleep in the backyard. I was surprised to find that I was not the only one, and most families who used artificial intelligence had this experience, as if artificial intelligence began to enslave human beings and threatened human security. This is definitely the biggest failure of artificial intelligence and human life application!
Artificial intelligence seems beautiful, but in fact there are all kinds of unknown dangers lurking. To some extent, the ability of intelligent learning has greatly approached and surpassed the ability of human beings. For this powerful technology, only by striving to improve its own ability can human beings really use this technology to benefit mankind.
At this moment, I want to continue to live with artificial intelligence in the right way.
