Method blind mathematicians
?
Maikejinlei like mathematicians, they can use mathematical methods in different situations, even if it is seen not know poker games, such as Pai Gow, they can go home to write code, and then come to an optimal strategy. On the way to find true love,http://sori.org/hangul/conv2kr.cgi, there should also be an optimal strategy. Maikejinlei on the use of an algorithm, big data and machine learning method based on a blind date website to find true love.

Compile _ seven cats
?
UCLA (University of California) math lab, Chris? Maikejinlei shrink between his office, a tiny bulb and screen mapping shimmer is the only three in the morning light. He's here to catch his doctoral thesis (title: "Big data processing and parallel computing method"). When the computer is busy compiling the code, he points to open another window to see his OkCupid inbox.
?
By the way, OkCupid is a matchmaking website.
?
Now let's introduce our hero: Maikejinlei, 35 years old, unmarried, she is dry, sparse hair, in appearance almost no competition. He is 40 million network dating a member of the army, from Match.com to J-Date and then e-Harmony, but all the little-known dating site, has his information. Since nine months ago in front of his girlfriend, Maikejinlei has been looking for a new fate, but always to no avail. There is a web site, OkCupid, who according to its algorithm to Maikejinlei recommended dozens of his "very good fit," the girl, but they are among the most Maikejinlei to have sent a message of self-introduction. Most people ignored his message; only six were with him on the first date, but no one can go further.
?
The early morning of June 2012, the Maikejinlei computer to compile the code, another window is deserted his dating site profile page alone. This time, he suddenly woke up, that he made a fatal mistake: he has, like other users of the online dating site, he now realizes that he should be as blind as a mathematician.

An algorithm to find your soul mate
?
In 2004, four students in mathematics at Harvard founded OkCupid, its selling point is the "use algorithms to find your soul mate." This site designed a number of attitudes and psychological test questions (they even developed a platform for members to create their own psychological test), members of ten required questions to be answered and several other additional problems. These questions are multiple choice, coverage include politics, religion, family, love, sex and even smart phone brand. For example, "Which of the following is most likely to attract you go to a movie?" Or "How important is religion and God in your life in the end?"
?
Members not only need to record their answers (radio), also you need to select an acceptable partner answers (multiple choice), and think how important this issue (from "no relationship" to "crucial"). According to statistics,scarpe hogan uomo, the average member of the site will answer 350 problems per person.
?
Answer the question, the more higher the accuracy of matching - based on the answers to these questions of data, OkCupid algorithm matching engine automatically measure between the two members, 100 percent is the soul mate mathematics, then, of course, the close to 100% as possible.
?
But even mathematically, Maikejinlei Match Los Angeles woman is very sad. Mainly because, OkCupid when selecting potential matches object, first lock answered the same question in the crowd,http://guizshj18.com/news/html/?31098.html, and then further screened based on gender, sexual orientation, and finally calculate the scores between the two on this issue in accordance with the answer. The problem is that Maikejinlei are randomly selected questions, and he answered the question, ultimately looks are "unwelcome" problem, that is, very few people to answer these questions. So, in a 200 million women in the big city, at least 80,000 women in the use OkCupid, but Maikejinlei the match by 90 points or more, less than 100. On a match is equivalent to the presence of the site, he is actually a transparent person.
?
He realized that he had to lift these numbers. It maikejinlei think he can be learned by statistical analysis which questions to him like a woman who is the most important, then he can build a new dating archives, honestly answer the "right" questions, then the other Problems do not have control. In theory, so he can be matched to any suit in Los Angeles, his wife, and not met anyone who does not fit.
?
Love has an optimal policy
?
Even for a mathematician, Maikejinlei also a very unusual person.
?
He grew up in suburban Boston, graduating in 2001 at the Department of Chinese Mead Bridgend College, the same year in August in New York to find a part-time job in the North Tower of the World Trade Center 91 layers of a company when the translation will be translated into Chinese English. In his fifth week into the community, hit the twin towers tragedy -? 9 11 day Maikejinlei go to 14:00 only need to go to work, so in the morning when the first plane hit 8:46 North Tower when he was still among sleep.
?
"After that day, I am going to ask myself, do I want in the end," Maikejinlei said.
?
Just, he had a Colombian friend saw his reaction and mathematics, he recruited into the famous MIT blackjack team (MIT Blackjack Team) - They rely on fast card counting skills and teamwork with playing cards Play blackjack in the casino to win large sums of money. After a few years, he and from New York and Las Vegas, you can earn up to $ 60,scarpe nike running,000 per year.
?
This experience deepened his interest in applied mathematics, and eventually encouraged him aggressive, more research in this area has been master or doctoral degree. "They are able to use mathematical methods in different situations," Maikejinlei mention his card counting in partner, said, "even if it is seen not know poker games, such as Pai Gow, they can go home to write code,http://bbs.wxsfw.com/forum.php?mod=viewthread&tid=12296, and then come to a optimal strategy. "
?
In his view, the way to find true love, but also an optimal strategy.
?
Science to find true love
?
First, he needs data. He established 12 virtual OkCupid account, and through a Python script to control them. This script will find his target (25 to 45 years between heterosexual and bisexual women), visit their website, crawl all public information: race, height, smoking, constellations, and so on.
?
To find the answer to their problems and that he must do something more. OkCupid allow users to see someone else's answer, but can only be answered their questions. So Maikejinlei let his code to manipulate the various accounts to answer random questions - anyway, he does not have these accounts to attract anyone's attention, so the answer is not important - then, the girls answer stored in its own database.
?
Maikejinlei satisfaction at his program a rewarding experience. However, he only collected a 1000 account information,http://www.1zhao.org/home.php?mod=space&uid=2112621, they encounter a new barrier: OkCupid has an anti-abuse system, designed to prevent such data harvesting, so not long before his virtual account can be one sealed.
?
He must train them like human beings.
?
He found his friend Sam? Torrisi. Torrisi also a wonderful person, he is a neurologist, but recently he Maikejinlei teaching music theory knowledge, exchange Maikejinlei have to give him a few lessons on several high church. Torrisi himself was on OkCupid partner,nike femme pas cher, he feels it makes sense to do Maikejinlei, agreed to install a computer in their own monitoring software, recording his usage. With this data, Maikejinlei can write a program to simulate Tuolei Xi mouse click speed and typing speed, in short, "it looks like a man." He again brought home a computer plugged into the Ethernet port on the Department of Mathematics, 24 hours so it can run without interruption.
?
Three weeks later, he was a good harvest, and now he has 20,000 girls across the country six million Questions and answers. The three o'clock sudden idea into a Maikejinlei another important project. He already regularly in the cubicle in the night,http://www.kijitsuhan.com, which, he simply does not renew the apartment directly, completely moved to the back room office. He took a thin little blanket, etc. to sleep, to sleep lying on the table.
?
Big data processing and true love category
?
To get Maikejinlei plan work, he needs to find a pattern in which 6 million question and answers, good girl this 20,000 into different categories. He began to experiment with different algorithms, eventually, when he found a modified version of Bell Labs K-Modes algorithm, the breakthrough came. This algorithm was first put into use in 1998, was used to analyze the specific reasons for disasters around the soybeans, which can feature based on large amounts of data, all objects slowly broken down subdivided into different types. With this algorithm, Maikejinlei can easily harvest to his data into different categories, find the most suitable for his woman in 20,000 people.
?
He began to practice. According to their questions and answers, 20,000 people have been gradually divided into 7 groups. Maikejinlei think this is enough, he has felt ecstatic about this progress, "it is the highest point in June."
?
Then he needs to do a repeat verification, so he gave the program a new task: the past month, there are 5,000 women in Los Angeles and the San Francisco area logged OkCupid. He brought K-Modes to forget again, the results prove that these people are in a similar way are divided into seven groups. In other words, he's algorithm is feasible!
?
In different categories,http://www.wd134.com/forum.php?mod=viewthread&tid=51247, he chose to study some files and found one too young, too old, then there are two, there is an overly pious religion. However, there is a category looks good: there are 25-year-old woman, it seems very personal, musicians or artists. They are the gold category, that is, the kind he wanted. He felt, where he could find true love.
?
In fact, there is another category looks pretty cool - there's a little larger older women, are engaged in creative occupations,boutique jordan, such as editing or designer. He decided to try both, so he created two accounts,http://www.caijicare.com/bbs/home.php?mod=space&uid=537095, respectively, for Class A and Class B optimization optimization.
?
He thumbed through these two categories of female archives, looking for something they are interested in. As a result, the original teacher is still very popular, so he stressed in the introduction, he was a professor of mathematics. Of course, the most important part is those issues. He was elected in both categories in the Top 500 issue, and then honestly answer - he did not want the future of love and marriage built on false. But in the end he decided to let the computer decide how important each issue, he used a machine learning algorithm, called "adaptive enhancement" (adaptive boosting), in order to get the best score.
?
Thus he created two accounts, one of which is his profile photo look like rock climbing, while the other is he playing the guitar. "No matter how the future plans, you are more interested in what is now? Sex, or love?" His answer is love. But for the younger category A, on the recommendation of his machine is rated "very important" for the B category, it is "crucial" for this problem.
?
When he answered the last question, he conducted a search on OkCupid, ordered by Match. Top: 99% Match a full page. He flip, flip again, 10,000 people passed, with his Match is still more than 90%.
?
He needs to do one thing to improve their degree of concern. OkCupid is such that if someone visits your page, you will receive a notification. So Maikejinlei write a new program to automatically access an object that matches the highest score, in descending order according to the age: Monday is 1000 41-year-old woman, Tuesday was 1000 40-year-old woman, so two weeks later, is a 1000 27-year-old woman, then repeat. Visit his page to quickly increase female, and sometimes up to 400 people every day, and his message box also into a lot of information.
?
"I have never seen such a high degree of matching with my people, and I think your information quite attractive," a woman wrote, "but a good man feeling rough math is always some story ...... I I feel that they have to say hello to you. "
?
"Hey - your data looks really interesting to me, so I wanted to say" Another wrote, "I think a lot of common ground between us, although not mathematically, but other aspects, such as amazing! "
?
"You really can translate Chinese?" Another asked. "I've been to a class, but it is too difficult."
?
After meeting at the beginning of love
?
Part mathematics and algorithms to this end. Maikejinlei looking for love on the road, he needs to do one thing: to leave his cell Quartet Workshop - dating.
?
June 30, 2012, at UCLA stadium Maikejinlei took a shower, then went to see his first Dating, Sheila. She is a designer, A category, the kind of young artist types. They Echo Park (Echo Park) was a cafe lunch date. "Actually I was a little scared," Maikejinlei recalled, "to the time before, this has been like a scholarly project."
?
But when he told Sheila farewell, it is clear that they are not fond of each other. So the next day he made his second date is a blog writer from the B category. He intended to echo the lakeside park with a female companion in a romantic stroll conversation, but to get there only to find, is a group of people digging silt in the lake. Worse, she loves the French writer Marcel? Proust, very positive attitude toward life. Maikejinlei said the appointments even feel some depression.
?
Dating to the 20th when he found A category of people inside, many have tattoos, or kept in a large dog, but he is very capable of these things are not acceptable. A month later, he thinks these wrong people hindered his efficiency, he deleted his account categories A, B categories of people to concentrate on dating. His efficiency is improved,http://www.lt1228.com/home.php?mod=space&uid=440505, but the result is still the same. He has been dating for 55 people, but only saw the second plane with three people, only one person will be about a third.
?
Most failed appointments cast doubt on life, but for Maikejinlei, this is worse, he began to doubt their own algorithms.
?
Until he received Wang Tian (phonetic) information. She is a 28 year-old artist, activist prison or repeal movement. She is reading UCLA Master of Arts, near UCLA hopes to find about 180cm tall blue-eyed guy, then she found the Maikejinlei. Their match was 91 degrees.
?
They are about to meet on campus sculpture park. From there, they walked together up a campus sushi chain. He immediately felt the love of power. They discussed from books to art and music, chatting chatting, she admitted before send him a message,nike air force one, she specifically on their own data to make a minor change; then he told her of his love algorithm from scratch to the end, the whole story.
?
"This thing can be really a little nervous," she said, "but I like it."
?
She is the 88th individual Maikejinlei date. But with the previous 87 individuals are different, they had a second date, third, two weeks later, they were freezing their OkCupid account.
?
"I think I do not much different from other people, just based on algorithms, big data and machine learning version" Maikejinlei represents. Everyone wants to create a more optimal account information on the dating site, he just created a data and programs.
?
For Wang Tian, the Maikejinlei feat just an interesting story. She knew that these mathematical and programming are just let them meet preface the story, the real challenge is life after they met. "Human far more complicated than those of information on the account," she said. "So, the way we met some components might have unreal, but after that every moment is very real."
?
Maikejinlei also agree with her: "Not because we have a good relationship matching, but, this algorithm allows us to stand where I can reach each other using OkCupid found the right person.."
?
She knocked on his elbow disapprovingly: "You do not find me, because I found you." Maikejinlei thought a moment, to admit that she said was right.
?
Now Maikejinlei has gained his doctorate, continue to teach mathematics; and Wang Tian, Qatar conducted a year-long partnership activities. In the week after the meeting with reporters, Wang Tian returned to Qatar, but in their daily conversations in Skype, Maikejinlei suddenly pulled out a diamond ring, in front of the camera.
?
She said she was willing.
?
They have not decided the specific wedding date; maybe they need an algorithm to optimize.
