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, and the pervasive coverage of Wi-Fi signals, more and more people no longer have the distinction between "online time" and "offline time", and they can hang online almost 24 hours if they want; The popularity of online services such as online trading, online payment and online registration has facilitated users, but it has also made people more dependent on the network and various online platforms.
With the development of science and technology, the information previously stored in several boxes of floppy disks or a CD-ROM can now be stored in a chip the size of a fingernail, which is more than enough. Digital information carriers that used to require computers, monitors, card readers and other special equipment to read may now only need a smart phone and a free third-party APP to 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 and credit cards with chip storage, new passports and driver's licenses, social security cards with chip reading function, 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. Simply put, in the past, the thinking decision-making mode was based on "why", but in the era of "big data", we can draw conclusions 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, under the mode of "only asking what is there, not asking why", it is likely that "catastrophic big data" will appear, that is, making wrong predictions and decisions because of the data itself.
If I can help you, I hope you can adopt it! Thank you)

Don't write too easily,
Write a 500-word article about selling newspapers. On Sunday, Li Chengti and I went to Xinlei Park to sell newspapers. If you think we are penny lovers, you are wrong, because we are doing a charity sale for the Enlai Love Foundation.
Li Cheng and I got on the bus at two in the afternoon. When we were about to get off the bus, an uncle asked me, "What newspaper is this?" Li Cheng and I said in unison, "This is Dahe Daily", and my uncle asked, "How much is it?" I said, "One dollar each." My uncle said, "Give me one." I was so excited that I quickly put away one yuan and gave the newspaper to my uncle.
After getting off the bus, we first came to the unnamed garden. I think old people love reading newspapers, so at first we specifically asked the old people, "Grandpa, do you read newspapers?" Dahe newspaper, one yuan each. "But some grandfathers said they couldn't see clearly without glasses, and some directly said they wouldn't buy it. When I was a little discouraged, an old man said, "How much is your newspaper, little friend?"? "I quickly said a dollar, and the grandfather bought it. We asked several people, but they didn't buy it.
Mom says you shouldn't just look for old people. Young people also love reading newspapers. You should ask them one by one. It doesn't matter if they don't buy it. What are you afraid of? As soon as I thought about it, we asked everyone, do you want to buy a newspaper? Because we wanted to see if we could sell our own newspapers, we didn't tell anyone that we were having a charity sale. At this moment, I heard an old woman say to her grandson, "Look, others know how to make money at such a young age. What about you? As soon as I heard it, I quickly said, "Grandma, we are not trying to make money ..." My grandmother gave me a quick wink. It turns out that grandma is to educate her grandson who loves to spend money recklessly. Unexpectedly, we became role models for others to learn. The old lady also bought one of our newspapers. We also met our kindergarten teacher, who also bought our newspaper. Several uncles and aunts bought our newspaper without waiting for me to speak. At that time, they felt very fulfilled.
Finally, we went to Xinlei Park, where there were many people. In a short time, all twenty newspapers were sold out. We count the money, one * * *, and there are twenty dollars. Looking at the hard-won fruits of labor, my mood can't be expressed in words. How many miles have we run to sell these twenty newspapers! It's really not easy to make money, and you can't spend money indiscriminately in the future.
Write a paper with the theme of Guizhou pharmaceutical environment investigation under the background of big data, with more than 2000 words. Send me your documents and I will help you.
Write an article of 1300 words on the topic of the blessings of college graduates. It's June. It is a day that graduates miss but have to leave. Last year, I saw my friends say goodbye and wish each other well. I didn't expect time to pass so quickly, and it was my turn to leave in a blink of an eye. I wonder if my friends are blessing me, too?
Yesterday, I went to farewell dinner, and my heart was sour, because many students didn't come. Some people are excusable for not getting a diploma, but what about others? I don't know if they really have something to do or if they don't care about their classmates for four years. However, almost all my brothers came. I'm not disappointed, just a little disappointed. Almost everyone has had this disappointment, because it seems that the quality of the food is not so good, and the waiter began to serve fruit without seeing a few pieces of meat. I am a very emotional person, hehe, I didn't expect my graduation party to be as lively as our football team going out to eat!
I still can't figure out the school arrangement. In May, we were very busy with graduation design, but in June, we were too idle. It is said that senior graduates have found jobs and lived their daily lives like pigs. It's true. We are like a group of lazy pigs, quietly waiting for the school to issue us a diploma in July. But the school seems to have let us be pigs for too long. What can we do except complain? Too leisurely life tends to degenerate, especially for a loner like me, sometimes it is really boring and disheartened, even if there is a wonderful World Cup for me to enjoy at night. Loneliness is terrible, and I am also a person who is afraid of loneliness, but after all, I can't find some ways to eliminate loneliness or minimize loneliness. Maybe this is my incompetence. I am a brave man. But I am a person who lacks courage or confidence. In college life, I gave up many things. Objectively speaking, it is difficult for me to give up what I want. To put it mildly, maybe this is called giving up after giving up. For a young student like me, learning and feelings are the most important things in life, but for both, I do more passively than actively. Many victories were won in injury time. Looking at the hard-working spirit of the stars on the field, I realized many of my shortcomings and finally realized a great spirit, that is, never give up. Really, I'm still far from it!
Today, when I was packing, I saw the letter from my first girlfriend and read it carefully with nostalgia. I was deeply moved. Seeing some angry words she said seemed to make me see her angry again. She is beautiful and good to me. I once loved her deeply, and of course she loved me deeply. Maybe I really didn't understand her well before, no matter whether the decision I made was right or wrong. After all, I gave up a woman who could affect my life. Looking back four years ago today, how happy I am. Now that I think about it, it really smells like the past is unbearable. Now that people have grown up, they understand a lot of things. I know that many times we can't help it. I think the ups and downs of life are here!
The quadrennial World Cup is coming again. Although the champion will be decided soon, he will come back four years later, giving people more expectations. But my college life is fixed in the four years from 2004 to 2008. Just like this, it doesn't matter what happened before or now. Those girls I once loved, those brothers who loved me, I will bless you in the north. I will work hard, because what I need is a * * * four years!
Write a 900-word article about my hometown xx. My hometown is in a small mountain village, where there are beautiful scenery, mountains and waters, flowers and grass, and trees, dates, peaches and apricots are everywhere. I love my beautiful hometown, but I love apricot trees in my hometown more.
In spring, it drizzles like silk. Apricot trees greedily suck the dew of spring. They spread the green leaves. With the breeze blowing, the branches sway gently, as if laughing in this sweet spring rain, which is particularly charming.
Apricot trees bloom in March and April every year. Apricot trees are different from ordinary trees. They bloom first and then grow leaves. Beautiful flowers, white and pink, look like umbrellas from a distance, which is especially beautiful. A gust of wind blew, and a faint fragrance came face to face. The fresh taste is intoxicating.
After the Dragon Boat Festival, apricot trees are full of fruits. The fruit looks particularly tender when it is small, especially when it is sunny after rain. Little green apricots hang upside down on the tree, like green shining gems. When Xinger grows up, his head is as big and red as a small peach, but not as sharp as a peach. Strangely, there is a big hole in his stomach, as if he had been cut by something, which makes people feel very distressed. Without ripe apricots, it feels as if his teeth are going sour. But ripe apricots are different. It tastes sweet and delicious.
I remember asking my father why Xinger has two sides. One side is red and the other side is green. The red side is much sweeter than the green side. Dad said, "The red side is sunned, and the green half is not sunned." Dad also said that the lost person can also find the direction according to this, and the apricot tree can help him find out which is south and which is north. I think, the role of apricot trees is still quite big.
Whenever I walk into the market, I will hear "Xinger sellers, apricots sellers ...". When people pass by, whether they are pushing carts, carrying bags or in a hurry, they will stop to buy some and take them back to taste.
I like apricots in my hometown.
About 400-word essay on the theme of big data "Changes of big data after several years" In the past two weeks, I read the book "The Age of Big Data" recommended by Mr. Dewey in my spare time. I read it quickly and found something I didn't expect to see.
First of all, big data represents data = all samples, which is significantly different from traditional statistics. Big data has the ability to get all the information and analyze it.
The second is that correlation is as important as causality. Correlation shows what is related to what, such as the correlation between the increase of traffic around the mall and the sales of the mall, and causality shows that what is what, such as sleeping for 10 hours is the mental reason. In big data, correlation is easier to obtain than causality, and correlation can already bring greater benefits to customers.
The third is to allow big data to be inaccurate and mixed. Due to the huge amount of data, a small amount of variation will not have any impact on the results. For example, the income difference between 65,438+billion and 65,438+billion in 0 yuan may not be of concern to policy makers.
The fourth is the three main factors in big data, thinking, data and technology. Where does thinking think you use big data? Among these three factors, there will be a data middleman to process and sell the processed data.
Write an article of 1000 words with the theme of discovering the beauty of Xiangtan. Xiangtan is beautiful all year round!
In spring, the green leaves are pulled out from the trees, and the breeze blows over your face, which is very comfortable! In the morning,
Dewdrops on the trees are like sparkling white pearls, and some use leaves as slides on the local floor.
The surface slides around, and some use leaves as a stage to roll on it.
In summer, the trees are so dense that they block everyone's view. Evening, old man
Holding fans, everyone enjoys the cool under the tree, and it is as lively as an ocean.
In autumn, the leaves on the trees turn yellow, the fruits are ripe, the pears are fragrant and the apples are sweet.
Yes, autumn is really like a fruit house.
In winter, the branches are covered with thick snow, just like Mother Earth is covered with a big tree.
White quilt, white snow under the tree, very comfortable to step on!
The four seasons in Xiangtan are beautiful, and I like it here!
As soon as I wrote an article with the theme of "Breakthrough and Leap" of 300 to 500 words, the autumn wind was mixed with faint osmanthus fragrance. Intoxicating,
Maybe this is the unique taste of the countryside.
Last night, I heard that they were going to pick hawthorn on the mountain today, which was a big deal for me.
Something new that has never been heard before. The habit of being lazy in bed before has long been forgotten, and I
Can't wait to get ready to go.
Along the mountain, although the road is narrow, only two or three people can walk side by side. Although it is only
More than 200 meters, but the slope is steep and the mountain road is rugged. I don't care about excitement.
After all this, I began to run to the top of the mountain, leaving my mother and uncle behind.
Finally, he reached the hawthorn forest, and uncle climbed the hawthorn tree flexibly, split it with a knife, and the tree
The branches and hawthorn fell to the ground together. I was so happy to pick up hawthorn, but I didn't expect another tree to fall.
Branches, too late to escape, I was badly scratched by branches, I was angry and turned around.
The head ran back.
I came to that mountain road again, steeper, more rugged and longer than before.
..... I climbed up the weeds on the right with my hands, and my feet moved slowly, and bang, my feet.
The sand on the floor slipped me, and I quickly grabbed the grass with my hand. But "plop" is still a lifetime.
I fell to the ground. I looked down at the cliff on the left, at least 20 meters. I can't help crying.
Speak out loud, there is nothing you can do sitting on the road. That is a high mountain, which I have never crossed.
The mountain dried my tears, and I stood up and walked down the mountain step by step. fertile/rich/fecund soil
However, I found there were stones and wood around, and maybe the situation was not so bad. I am very nervous
Hold fast to the surrounding grass and dare not relax. Cold sweat. Although the road ahead is dangerous, I
There is only one way-to move on. I tried to put my foot on that piece of wood,
Holding the grass tightly in my hand is like my lifeline. Step by step, I
I feel extremely stable. So, I followed the road to the next step. Through the rock, I jumped up again.
On the relatively stable ground ... I don't know how long it took, and how much sweat came out of my palm.
I've already gone that way. I finally crossed the first mountain, and I finally took the first step.
Conquered the fears and obstacles in my heart.
I got a lot of encouragement. No matter how hard it is, it doesn't matter only
Believe in yourself, everything is enough.
